Oh, by overlaps I meant it was landing on the same point; for example if you had two at 50,50 or something like that.
I could probably rewrite it in C++ and test it after I finish some project work (dont know enough java to modify it)
seededRandom is not random at all.

Thanks! I've changed seededRandom to use your algorithm in the next beta. It's way better now.pixelfck wrote:...
Meanwhile, I did a quick extension to display randomness, based on your JavaScript code: https://www.dropbox.com/s/29buowdqmeuzt ... ssTest.xml
To use it:
1. Drop the file in Extensions
2. Start a new game
3.
4. Click on the "Randomness" menu item.

@Wolfy: thanks! (it is javascript, not Java; so the algorithmic operators should be the same as in c++).
Anyhow, I would be interested to see what algorithm you came up with that passes all the diehard tests, I think it is quite a feat.
@george
Nice, I'll put it to good use!

Here's the results from diehard for yours (seed 123412341234  assuming order of operations was the same)
While the rate of outlier p values (p < 0.01 or p> 0.99) was high for the number of samples (also there were two p=1.000000 values [See DNA tests for bits 3230]), its probably sufficient levels of randomness for transcendence as well as being far faster than mine. (I tested; yours is ~34 orders of magnitude faster than mine)

(I tested; yours is ~34 orders of magnitude faster than mine)
Code: Select all
NOTE: Most of the tests in DIEHARD return a pvalue, which
should be uniform on [0,1) if the input file contains truly
independent random bits. Those pvalues are obtained by
p=F(X), where F is the assumed distribution of the sample
random variable Xoften normal. But that assumed F is just
an asymptotic approximation, for which the fit will be worst
in the tails. Thus you should not be surprised with
occasional pvalues near 0 or 1, such as .0012 or .9983.
When a bit stream really FAILS BIG, you will get p's of 0 or
1 to six or more places. By all means, do not, as a
Statistician might, think that a p < .025 or p> .975 means
that the RNG has "failed the test at the .05 level". Such
p's happen among the hundreds that DIEHARD produces, even
with good RNG's. So keep in mind that " p happens".

:: This is the BIRTHDAY SPACINGS TEST ::
:: Choose m birthdays in a year of n days. List the spacings ::
:: between the birthdays. If j is the number of values that ::
:: occur more than once in that list, then j is asymptotically ::
:: Poisson distributed with mean m^3/(4n). Experience shows n ::
:: must be quite large, say n>=2^18, for comparing the results ::
:: to the Poisson distribution with that mean. This test uses ::
:: n=2^24 and m=2^9, so that the underlying distribution for j ::
:: is taken to be Poisson with lambda=2^27/(2^26)=2. A sample ::
:: of 500 j's is taken, and a chisquare goodness of fit test ::
:: provides a p value. The first test uses bits 124 (counting ::
:: from the left) from integers in the specified file. ::
:: Then the file is closed and reopened. Next, bits 225 are ::
:: used to provide birthdays, then 326 and so on to bits 932. ::
:: Each set of bits provides a pvalue, and the nine pvalues ::
:: provide a sample for a KSTEST. ::

:: THE BITSTREAM TEST ::
:: The file under test is viewed as a stream of bits. Call them ::
:: b1,b2,... . Consider an alphabet with two "letters", 0 and 1 ::
:: and think of the stream of bits as a succession of 20letter ::
:: "words", overlapping. Thus the first word is b1b2...b20, the ::
:: second is b2b3...b21, and so on. The bitstream test counts ::
:: the number of missing 20letter (20bit) words in a string of ::
:: 2^21 overlapping 20letter words. There are 2^20 possible 20 ::
:: letter words. For a truly random string of 2^21+19 bits, the ::
:: number of missing words j should be (very close to) normally ::
:: distributed with mean 141,909 and sigma 428. Thus ::
:: (j141909)/428 should be a standard normal variate (z score) ::
:: that leads to a uniform [0,1) p value. The test is repeated ::
:: twenty times. ::

:: The tests OPSO, OQSO and DNA ::
:: OPSO means OverlappingPairsSparseOccupancy ::
:: The OPSO test considers 2letter words from an alphabet of ::
:: 1024 letters. Each letter is determined by a specified ten ::
:: bits from a 32bit integer in the sequence to be tested. OPSO ::
:: generates 2^21 (overlapping) 2letter words (from 2^21+1 ::
:: "keystrokes") and counts the number of missing wordsthat ::
:: is 2letter words which do not appear in the entire sequence. ::
:: That count should be very close to normally distributed with ::
:: mean 141,909, sigma 290. Thus (missingwrds141909)/290 should ::
:: be a standard normal variable. The OPSO test takes 32 bits at ::
:: a time from the test file and uses a designated set of ten ::
:: consecutive bits. It then restarts the file for the next de ::
:: signated 10 bits, and so on. ::
:: ::
:: OQSO means OverlappingQuadruplesSparseOccupancy ::
:: The test OQSO is similar, except that it considers 4letter ::
:: words from an alphabet of 32 letters, each letter determined ::
:: by a designated string of 5 consecutive bits from the test ::
:: file, elements of which are assumed 32bit random integers. ::
:: The mean number of missing words in a sequence of 2^21 four ::
:: letter words, (2^21+3 "keystrokes"), is again 141909, with ::
:: sigma = 295. The mean is based on theory; sigma comes from ::
:: extensive simulation. ::
:: ::
:: The DNA test considers an alphabet of 4 letters:: C,G,A,T,::
:: determined by two designated bits in the sequence of random ::
:: integers being tested. It considers 10letter words, so that ::
:: as in OPSO and OQSO, there are 2^20 possible words, and the ::
:: mean number of missing words from a string of 2^21 (over ::
:: lapping) 10letter words (2^21+9 "keystrokes") is 141909. ::
:: The standard deviation sigma=339 was determined as for OQSO ::
:: by simulation. (Sigma for OPSO, 290, is the true value (to ::
:: three places), not determined by simulation. ::

:: THIS IS A PARKING LOT TEST ::
:: In a square of side 100, randomly "park" a cara circle of ::
:: radius 1. Then try to park a 2nd, a 3rd, and so on, each ::
:: time parking "by ear". That is, if an attempt to park a car ::
:: causes a crash with one already parked, try again at a new ::
:: random location. (To avoid path problems, consider parking ::
:: helicopters rather than cars.) Each attempt leads to either ::
:: a crash or a success, the latter followed by an increment to ::
:: the list of cars already parked. If we plot n: the number of ::
:: attempts, versus k:: the number successfully parked, we get a::
:: curve that should be similar to those provided by a perfect ::
:: random number generator. Theory for the behavior of such a ::
:: random curve seems beyond reach, and as graphics displays are ::
:: not available for this battery of tests, a simple characteriz ::
:: ation of the random experiment is used: k, the number of cars ::
:: successfully parked after n=12,000 attempts. Simulation shows ::
:: that k should average 3523 with sigma 21.9 and is very close ::
:: to normally distributed. Thus (k3523)/21.9 should be a st ::
:: andard normal variable, which, converted to a uniform varia ::
:: ble, provides input to a KSTEST based on a sample of 10. ::

also heres the mk3b algorithm I used (super slow though)  the different versions were just slight refinements that lowered the number of (0.5p0.5) < 1%  it also seems that 123412341234 is a particularly rough seed:

mk2: (didnt test, had a bug so just redid the part)
mk3: nomrP < 1% = 4 ____ normP < 0.1% = 3 (total number of outliers went down.. but the outliers got worse..)
mk3b: normP < 1% = 2 _____ normP < 0.1% = 0 (Reasonable results given the number of tests  also one was P=0.009.. so barely fell in that category at that..)
this one was slightly edited to run in C# so I could play around with doing some image stuff but I decided not to and just work on my class project instead >.>

Ok, so for fun (since I already know the standard c rand() function is awful I didnt bother to test it) I decided to try out the simple .net rng...
Turns out that pixels knocks it flat (with around the same runtime!)  even with its own two 1.0's, the standard .net one is... just look at it! The number of 1.000000's is... This is without a doubt a complete fail.

Code: Select all
NOTE: Most of the tests in DIEHARD return a pvalue, which
should be uniform on [0,1) if the input file contains truly
independent random bits. Those pvalues are obtained by
p=F(X), where F is the assumed distribution of the sample
random variable Xoften normal. But that assumed F is just
an asymptotic approximation, for which the fit will be worst
in the tails. Thus you should not be surprised with
occasional pvalues near 0 or 1, such as .0012 or .9983.
When a bit stream really FAILS BIG, you will get p's of 0 or
1 to six or more places. By all means, do not, as a
Statistician might, think that a p < .025 or p> .975 means
that the RNG has "failed the test at the .05 level". Such
p's happen among the hundreds that DIEHARD produces, even
with good RNG's. So keep in mind that " p happens".

:: This is the BIRTHDAY SPACINGS TEST ::
:: Choose m birthdays in a year of n days. List the spacings ::
:: between the birthdays. If j is the number of values that ::
:: occur more than once in that list, then j is asymptotically ::
:: Poisson distributed with mean m^3/(4n). Experience shows n ::
:: must be quite large, say n>=2^18, for comparing the results ::
:: to the Poisson distribution with that mean. This test uses ::
:: n=2^24 and m=2^9, so that the underlying distribution for j ::
:: is taken to be Poisson with lambda=2^27/(2^26)=2. A sample ::
:: of 500 j's is taken, and a chisquare goodness of fit test ::
:: provides a p value. The first test uses bits 124 (counting ::
:: from the left) from integers in the specified file. ::
:: Then the file is closed and reopened. Next, bits 225 are ::
:: used to provide birthdays, then 326 and so on to bits 932. ::
:: Each set of bits provides a pvalue, and the nine pvalues ::
:: provide a sample for a KSTEST. ::

:: THE BITSTREAM TEST ::
:: The file under test is viewed as a stream of bits. Call them ::
:: b1,b2,... . Consider an alphabet with two "letters", 0 and 1 ::
:: and think of the stream of bits as a succession of 20letter ::
:: "words", overlapping. Thus the first word is b1b2...b20, the ::
:: second is b2b3...b21, and so on. The bitstream test counts ::
:: the number of missing 20letter (20bit) words in a string of ::
:: 2^21 overlapping 20letter words. There are 2^20 possible 20 ::
:: letter words. For a truly random string of 2^21+19 bits, the ::
:: number of missing words j should be (very close to) normally ::
:: distributed with mean 141,909 and sigma 428. Thus ::
:: (j141909)/428 should be a standard normal variate (z score) ::
:: that leads to a uniform [0,1) p value. The test is repeated ::
:: twenty times. ::

:: The tests OPSO, OQSO and DNA ::
:: OPSO means OverlappingPairsSparseOccupancy ::
:: The OPSO test considers 2letter words from an alphabet of ::
:: 1024 letters. Each letter is determined by a specified ten ::
:: bits from a 32bit integer in the sequence to be tested. OPSO ::
:: generates 2^21 (overlapping) 2letter words (from 2^21+1 ::
:: "keystrokes") and counts the number of missing wordsthat ::
:: is 2letter words which do not appear in the entire sequence. ::
:: That count should be very close to normally distributed with ::
:: mean 141,909, sigma 290. Thus (missingwrds141909)/290 should ::
:: be a standard normal variable. The OPSO test takes 32 bits at ::
:: a time from the test file and uses a designated set of ten ::
:: consecutive bits. It then restarts the file for the next de ::
:: signated 10 bits, and so on. ::
:: ::
:: OQSO means OverlappingQuadruplesSparseOccupancy ::
:: The test OQSO is similar, except that it considers 4letter ::
:: words from an alphabet of 32 letters, each letter determined ::
:: by a designated string of 5 consecutive bits from the test ::
:: file, elements of which are assumed 32bit random integers. ::
:: The mean number of missing words in a sequence of 2^21 four ::
:: letter words, (2^21+3 "keystrokes"), is again 141909, with ::
:: sigma = 295. The mean is based on theory; sigma comes from ::
:: extensive simulation. ::
:: ::
:: The DNA test considers an alphabet of 4 letters:: C,G,A,T,::
:: determined by two designated bits in the sequence of random ::
:: integers being tested. It considers 10letter words, so that ::
:: as in OPSO and OQSO, there are 2^20 possible words, and the ::
:: mean number of missing words from a string of 2^21 (over ::
:: lapping) 10letter words (2^21+9 "keystrokes") is 141909. ::
:: The standard deviation sigma=339 was determined as for OQSO ::
:: by simulation. (Sigma for OPSO, 290, is the true value (to ::
:: three places), not determined by simulation. ::

:: THE 3DSPHERES TEST ::
:: Choose 4000 random points in a cube of edge 1000. At each ::
:: point, center a sphere large enough to reach the next closest ::
:: point. Then the volume of the smallest such sphere is (very ::
:: close to) exponentially distributed with mean 120pi/3. Thus ::
:: the radius cubed is exponential with mean 30. (The mean is ::
:: obtained by extensive simulation). The 3DSPHERES test gener ::
:: ates 4000 such spheres 20 times. Each min radius cubed leads ::
:: to a uniform variable by means of 1exp(r^3/30.), then a ::
:: KSTEST is done on the 20 pvalues. ::

Now, if you want to see something especially abysmal, these are the results from randu! (again for seed 123412341234)
http://en.wikipedia.org/wiki/RANDU
http://en.wikipedia.org/wiki/RANDU
Code: Select all
NOTE: Most of the tests in DIEHARD return a pvalue, which
should be uniform on [0,1) if the input file contains truly
independent random bits. Those pvalues are obtained by
p=F(X), where F is the assumed distribution of the sample
random variable Xoften normal. But that assumed F is just
an asymptotic approximation, for which the fit will be worst
in the tails. Thus you should not be surprised with
occasional pvalues near 0 or 1, such as .0012 or .9983.
When a bit stream really FAILS BIG, you will get p's of 0 or
1 to six or more places. By all means, do not, as a
Statistician might, think that a p < .025 or p> .975 means
that the RNG has "failed the test at the .05 level". Such
p's happen among the hundreds that DIEHARD produces, even
with good RNG's. So keep in mind that " p happens".

:: This is the BIRTHDAY SPACINGS TEST ::
:: Choose m birthdays in a year of n days. List the spacings ::
:: between the birthdays. If j is the number of values that ::
:: occur more than once in that list, then j is asymptotically ::
:: Poisson distributed with mean m^3/(4n). Experience shows n ::
:: must be quite large, say n>=2^18, for comparing the results ::
:: to the Poisson distribution with that mean. This test uses ::
:: n=2^24 and m=2^9, so that the underlying distribution for j ::
:: is taken to be Poisson with lambda=2^27/(2^26)=2. A sample ::
:: of 500 j's is taken, and a chisquare goodness of fit test ::
:: provides a p value. The first test uses bits 124 (counting ::
:: from the left) from integers in the specified file. ::
:: Then the file is closed and reopened. Next, bits 225 are ::
:: used to provide birthdays, then 326 and so on to bits 932. ::
:: Each set of bits provides a pvalue, and the nine pvalues ::
:: provide a sample for a KSTEST. ::

:: THE BITSTREAM TEST ::
:: The file under test is viewed as a stream of bits. Call them ::
:: b1,b2,... . Consider an alphabet with two "letters", 0 and 1 ::
:: and think of the stream of bits as a succession of 20letter ::
:: "words", overlapping. Thus the first word is b1b2...b20, the ::
:: second is b2b3...b21, and so on. The bitstream test counts ::
:: the number of missing 20letter (20bit) words in a string of ::
:: 2^21 overlapping 20letter words. There are 2^20 possible 20 ::
:: letter words. For a truly random string of 2^21+19 bits, the ::
:: number of missing words j should be (very close to) normally ::
:: distributed with mean 141,909 and sigma 428. Thus ::
:: (j141909)/428 should be a standard normal variate (z score) ::
:: that leads to a uniform [0,1) p value. The test is repeated ::
:: twenty times. ::

:: The tests OPSO, OQSO and DNA ::
:: OPSO means OverlappingPairsSparseOccupancy ::
:: The OPSO test considers 2letter words from an alphabet of ::
:: 1024 letters. Each letter is determined by a specified ten ::
:: bits from a 32bit integer in the sequence to be tested. OPSO ::
:: generates 2^21 (overlapping) 2letter words (from 2^21+1 ::
:: "keystrokes") and counts the number of missing wordsthat ::
:: is 2letter words which do not appear in the entire sequence. ::
:: That count should be very close to normally distributed with ::
:: mean 141,909, sigma 290. Thus (missingwrds141909)/290 should ::
:: be a standard normal variable. The OPSO test takes 32 bits at ::
:: a time from the test file and uses a designated set of ten ::
:: consecutive bits. It then restarts the file for the next de ::
:: signated 10 bits, and so on. ::
:: ::
:: OQSO means OverlappingQuadruplesSparseOccupancy ::
:: The test OQSO is similar, except that it considers 4letter ::
:: words from an alphabet of 32 letters, each letter determined ::
:: by a designated string of 5 consecutive bits from the test ::
:: file, elements of which are assumed 32bit random integers. ::
:: The mean number of missing words in a sequence of 2^21 four ::
:: letter words, (2^21+3 "keystrokes"), is again 141909, with ::
:: sigma = 295. The mean is based on theory; sigma comes from ::
:: extensive simulation. ::
:: ::
:: The DNA test considers an alphabet of 4 letters:: C,G,A,T,::
:: determined by two designated bits in the sequence of random ::
:: integers being tested. It considers 10letter words, so that ::
:: as in OPSO and OQSO, there are 2^20 possible words, and the ::
:: mean number of missing words from a string of 2^21 (over ::
:: lapping) 10letter words (2^21+9 "keystrokes") is 141909. ::
:: The standard deviation sigma=339 was determined as for OQSO ::
:: by simulation. (Sigma for OPSO, 290, is the true value (to ::
:: three places), not determined by simulation. ::

:: This is the COUNTTHE1's TEST on a stream of bytes. ::
:: Consider the file under test as a stream of bytes (four per ::
:: 32 bit integer). Each byte can contain from 0 to 8 1's, ::
:: with probabilities 1,8,28,56,70,56,28,8,1 over 256. Now let ::
:: the stream of bytes provide a string of overlapping 5letter ::
:: words, each "letter" taking values A,B,C,D,E. The letters are ::
:: determined by the number of 1's in a byte:: 0,1,or 2 yield A,::
:: 3 yields B, 4 yields C, 5 yields D and 6,7 or 8 yield E. Thus ::
:: we have a monkey at a typewriter hitting five keys with vari ::
:: ous probabilities (37,56,70,56,37 over 256). There are 5^5 ::
:: possible 5letter words, and from a string of 256,000 (over ::
:: lapping) 5letter words, counts are made on the frequencies ::
:: for each word. The quadratic form in the weak inverse of ::

:: This is the COUNTTHE1's TEST for specific bytes. ::
:: Consider the file under test as a stream of 32bit integers. ::
:: From each integer, a specific byte is chosen , say the left ::
:: most:: bits 1 to 8. Each byte can contain from 0 to 8 1's, ::
:: with probabilitie 1,8,28,56,70,56,28,8,1 over 256. Now let ::
:: the specified bytes from successive integers provide a string ::
:: of (overlapping) 5letter words, each "letter" taking values ::
:: A,B,C,D,E. The letters are determined by the number of 1's, ::
:: in that byte:: 0,1,or 2 > A, 3 > B, 4 > C, 5 > D,::
:: and 6,7 or 8 > E. Thus we have a monkey at a typewriter ::

:: THIS IS A PARKING LOT TEST ::
:: In a square of side 100, randomly "park" a cara circle of ::
:: radius 1. Then try to park a 2nd, a 3rd, and so on, each ::
:: time parking "by ear". That is, if an attempt to park a car ::
:: causes a crash with one already parked, try again at a new ::
:: random location. (To avoid path problems, consider parking ::
:: helicopters rather than cars.) Each attempt leads to either ::
:: a crash or a success, the latter followed by an increment to ::
:: the list of cars already parked. If we plot n: the number of ::
:: attempts, versus k:: the number successfully parked, we get a::
:: curve that should be similar to those provided by a perfect ::
:: random number generator. Theory for the behavior of such a ::
:: random curve seems beyond reach, and as graphics displays are ::
:: not available for this battery of tests, a simple characteriz ::
:: ation of the random experiment is used: k, the number of cars ::
:: successfully parked after n=12,000 attempts. Simulation shows ::
:: that k should average 3523 with sigma 21.9 and is very close ::
:: to normally distributed. Thus (k3523)/21.9 should be a st ::

Nice to see those results. I'm a bit surprised by the failure of the .net rng. I would think that by now a standard rng would provide better quality output.
I'm most happy to see that my seededRandom is not that bad, although it seems that it is not particularly good either
It seems you put a lot more work in your, I'll take a better look at it later today.
Cheers,

For its speed, its great  Generally failing one test with a simple fast algorithm isnt bad  I was working on getting mine to produce a distribution of pvalues that were appropriate (ie, a combination that should only happen 10% of the time should only happen ~10% of the time, etc), but at the cost of it plodding along slowly.
