Activity

Chronicle

• On 2 October 2024, May made the initial commit and began laying out the repository structure with basic range functionalities and hand conversion utilities.^[1][2][3]
• Between 3 and 11 October 2024, May extended range equity calculations to handle multiple streets, added concentration-based abstractions for hand ranges, and implemented Monte-Carlo simulation methods for equity estimation.^{[4][5][6][7][8]}
• Between 14 and 16 October 2024, May implemented K-Means clustering for preflop hand abstractions and computed preflop equities using both Monte-Carlo and square root-based evaluation methods.^[9][10][11]
• Between 2 November and 4 December 2024, May built a MiniMax solver with alpha-beta pruning, node heuristics for game tree evaluation, and implemented a non-iterative approach to game solving.^{[12][13][14][15]}
• On 4 December 2024, May submitted a final project implementation combining the range utilities, equity calculations, and MiniMax solver.^[16]
• On 2 November 2025, May formalized the repository's documentation and configuration.^[17]
• Between 12 and 24 March 2026, May implemented a counterfactual regret minimization solver for heads-up no-limit hold'em, removed the legacy MiniMax engine, added street-specific bet sizing and a subgame solver, and created a web frontend with bot evaluation and command-line game interfaces.^{[18][19][20][21]}
