Exact Counting
Exact counts of astronomically large, rule-bound spaces — computed and verified on a desktop.
Ten years of building a general-purpose engine for exact counting: how many valid members does a constrained space really have, when that space is far too large to ever enumerate? Posts here cover results and the verification gates behind them — famously hard combinatorial problems with independently published answers are the proving ground, because they leave nowhere to hide.
