The acme-memorandom package

[Tags:library, mit]

A library for generating random numbers in a memoized manner. Implemented as a lazy table indexed by serialized StdGen. Monomorphism is used to facilitate memoization, users should adapt their design to work with random Int values only.

In a benchmark, the initial generation of 100000 random Ints took 10.30 seconds and consumed 2.5 gigabytes of memory. Generating the 100000 Ints again from the same seed only took 2.06 seconds, a 5-fold speedup thanks to memoization!

Incidentally, generating the 100000 Ints with the non-memoized function took 0.12 seconds, but that of course lacks all the benefits of memoization.
