A canopy pseudo-random number generator. Using the Tausworthe exclusive-or shift register, a simple Integer Coungruence generator, and the Hurd 288 total bit shift register, all XOR'd with each other, we provide an engine that should be a fairly good "mother" generator.
This is similar to DualRand, with the addition of the Hurd288Engine. From DualRand, we have the following:
Exclusive or of a feedback shift register and integer congruence random number generator. The feedback shift register uses offsets 127 and 97. The integer congruence generator uses a different multiplier for each stream. The multipliers are chosen to give full period and maximum "potency" for modulo 2^32. The period of the combined random number generator is 2^159 - 2^32, and the sequences are different for each stream (not just started in a different place).
The above is then amended to also add in the exclusive or of the 288-total bit Hurd engine which in this case is a series of 32 interconnected 9-bit shift registers, with the newest bit of each register formed by the XOR of the previous bit and some bit b-d from a previous register where d is chosen to create a primitive polynomial to maximize the period.
