eval.gnubg_harness

eval.gnubg_harness

Automated money-game sessions against GNUBG via the gnubg-nn package.

This is the M6 benchmark harness. Raccoon (driven by MCTS on a RaccoonNet) plays a cubeless money game against GNUBG’s neural-net evaluator. Gammons and backgammons are scored (2x / 3x) via OpenSpiel’s terminal_result.

The GNUBG FFI is isolated in raccoon.eval.gnubg_adapter so this module stays free of conditional imports.

gnubg_level is a friendly string (e.g. "world") mapped to a ply integer via gnubg_adapter.level_to_ply. Pass ply explicitly to override (0 = fastest, 2 = strongest).
