Struct EaaiSimpleBot 

pub struct EaaiSimpleBot<R> { /* private fields */ }

The reference baseline of the EAAI-2021 Gin Rummy challenge

A port of SimpleGinRummyPlayer from Todd Neller’s challenge framework: it ignores everything the opponent does, takes the face-up card only when it immediately joins a meld, sheds a uniformly random card among those leaving minimal deadwood — refusing to repeat a (draw, discard) pair within a round, the original’s loop breaker — and knocks at the first legal opportunity. It exists as a fixed measuring stick for comparisons across engines and papers, not as a good player, so there are no tuning knobs.

Departures from the Java original, none of which change its policy under the challenge rules: the knock spread is best_melds’s optimal arrangement rather than a random optimal one (this affects only which layoffs the defender is offered); layoffs use this crate’s greedy layoff in place of the framework’s automatic first-fit sweep; and the knock threshold follows View::knock_limit rather than a hardcoded 10, so the bot stays legal under any ruleset.

The EAAI framework has no big gin, so this bot never declares it; run benchmarks with big_gin_bonus: None for exactly the challenge’s round conditions.
