	The Free Information Society - Computer Generated Random Numbers
		The RANDU routine is considered obsolete and is now completely undocumented, but it still exists in the VMS FORTRAN Run-Time Library and will always exist to support any old programs which still use it.
		The algorithm RANDU uses to generate successive random numbers is: SEED = (65539SEED) MOD 231 X = SEED/231 This is a linear congruential generator with: A = 65539 C = 0 M = 231 Note first that the modulus M for RANDU* is 231 whereas the modulus M for MTH$RANDOM is 232.
		The obsolete RANDU generator does require an odd seed value, but for the MTH$RANDOM generator the seed value alternates between even and odd values at each iteration, so there is no advantage to starting with an odd value.

	RANDU - Wikipedia, the free encyclopedia
		RANDU is an infamous linear congruential pseudorandom number generator which has been used since the 1960s.
		It is widely considered to be one of the most ill-conceived random number generators designed.
		Notably, it does not have a full period, due to the poor choices of modulus and multiplier; it also fails the spectral test badly for dimensions greater than 2.

		Since the RAND or RANDU given to a peer are accompanied with the message authentication code AT_MAC, and since the peer's NONCE_MT value contributes to AT_MAC, the peer is able to verify that the Lizhiming [Page 7] Internet Draft EAP CAVE Authentication 15 April, 2004 EAP CAVE message is fresh (not a replay).

		The speed differences were randu rand53 rand53/randu Matlab R12 tic;x=rand(1e6,1);toc 0.072 0.110 1.53 0.087 tic;x=rand(5e6,1);toc 0.360 0.550 1.53 0.434 So there is a 53% slow up by doing this, and the octave code is now slower than Matlab.
		I'd thought that maybe we could regain the speed reduction by precalculating the factor "1.0/4294967296.0" in randu, and similarly in rand53 "1.0/9007199254740992.0".
		It should be noted that the state vector of randn in matlab is 2-element, and it appears it uses a simplier randu generator than the Mersenne Twister, so perhaps this speed difference is normal.

		RANDU was a multiplicative congruential generator with a = 65539 and m = 2147483648.
		Today, RANDU is used only as an example of how not to construct a PRNG.
		In addition, a comparison with RANDU is carried out, testing the randomness of individual bits.

		for the modulus were those made by the notorious pseudo-random number generator known as "RANDU", popular in the early 1970s.
		By rotating the figure (as described below), one can easily see what was wrong with this very popular generator.
		By contrast, go here to see an even worse variant of RANDU, and by contrast here to examine the so-called "Minimal Standard" to see a much better variant.

		His problem can be found at the top of page 416 ("A Universal Statistical Test for Random Bit Generators", proceedings of Crypto 90, pp.
		"The test can be implemented by using a table (denoted below as TAB) of size 2^L that stores for each L-bit block the time index of its most recent occurrence." Unfortunately for Maurer, RANDU has L=31, so he's building and using an array of 2^31 elements.

		Sometimes, but not always, modeling problems are noticed and lead to improvements in PRNGs.
