Combinatorial Game Theory (CGT) is a branch of mathematics that studies sequential games with perfect information. Combinatorial games include well-known rulesets like Amazons, Clobber, Domineering, Hackenbush, Konane, Nim, Octal Games, Wythoff’s Nim. After John Conway's On Numbers and Games (1976), Elwyn Berlekamp, John Conway, and Richard Guy published “the book” Winning Ways (1982). In that work, one can find a unified mathematical theory able to analyze a large class of rulesets. The books Lessons in Play (2007), by Michael Albert, David Wolfe, and Richard Nowakowski, and Combinatorial Game Theory (2013), by Aaron Siegel, are also mandatory reading.
Combinatorial Game Theory Colloquia are held every two years, in Portugal. Associação Ludus will organize in S. Miguel, Azores, the fourth edition of the CGTC, 18-20 January, 2021, with support of Centro de Análise Funcional, Estruturas Lineares e Aplicações, Centro de Matemática Aplicada à Previsão e Decisão Económica, Centro Interuniversitário de História das Ciências e da Tecnologia, and Núcleo Interdisciplinar da Criança e do Adolescente.
