Towards Understanding the Effects of Evolving the MCTS UCT Selection Policy

no code implementations7 Feb 2023 Fred Valdez Ameneyro, Edgar Galvan

A particular selection policy that works particularly well, widely adopted in MCTS, is the Upper Confidence Bounds for Trees, referred to as UCT.

Evolving the MCTS Upper Confidence Bounds for Trees Using a Semantic-inspired Evolutionary Algorithm in the Game of Carcassonne

no code implementations29 Aug 2022 Edgar Galván, Gavin Simpson, Fred Valdez Ameneyro

In this work, we use Evolutionary Algorithms (EAs) to evolve mathematical expressions with the goal to substitute the UCT formula and use the evolved expressions in MCTS.

Statistical Tree-based Population Seeding for Rolling Horizon EAs in General Video Game Playing

no code implementations30 Aug 2020 Edgar Galván, Oxana Gorshkova, Peter Mooney, Fred Valdez Ameneyro, Erik Cuevas

Furthermore, we tackle the former limitation by employing a mechanism that allows us to seed part of the population using Monte Carlo Tree Search, a method that has dominated multiple General Video Game AI competitions.
