2-hato-1 principles
Distribution of 2-int0-1 principles occurring in evolved three-bit multiplier
genotypes.
just one of a number of possible subcircuit histogram plots, but it is probably one
of the most fundamental.
Inspired by the obvious usefulness of gates 6, 7, and 10 (AND, AND with in-
verted input, and XOR) we ...
