Detailed Description

java.util.Random, the 48-bit LCG of the Java Language Specification.

The engine uses 23 of these alongside the MRG streams, for the choices that are draws rather than variates: which batch size a BMAP service releases, which branch a probabilistic route takes, and so on. Transcribed rather than approximated, for the same reason as above.
