Implementation of counterfactual regret minimization (CFR) for Texas hold'em poker

Algorithm

• CFR+
• Supports multi-thread
• Precomputed heads-up equity
• Written in Rust (fast and safe)

Files

• cfr.rs

The main logic of counterfactual regret minimization is described.

• main_kuhn.rs ($ cargo run --release)

Solve Nash equilibrium of Kuhn poker (mainly for testing).

• main_push_fold.rs ($ cargo run --release --bin push_fold)

Solve Nash equilibrium of heads-up push/fold hold'em, i.e., the heads-up poker only allowed to push (all-in) or fold.

• main_preflop.rs ($ cargo run --release --bin preflop)

Solve Nash equilibrium of pre-flop only heads-up hold'em, i.e., every player checks after flop opens. Currently, the bet size is limited to 2.5x, 3x, 3.5x, 4x, and all-in.

• main_viewer.rs ($ cargo run --release --bin viewer)

Open a CUI interactive viewer for pre-flop strategies computed by main_preflop.rs. It reads data in output directory.
