Jean-Christophe Weill introduced the NegaC* search algorithm as a NegaMax implementation of Kevin Coplan's **C***. He also created the ABDADA non-synchronized, distributed search algorithm, apparently used in Frenchess. His 1995 Ph.D. thesis in French, //Programmes d'Échecs de Championnat: Architecture Logicielle Synthèse de Fonctions d'Évaluations, Parallélisme de Recherche//, covers history of computer chess, a broad range of search algorithms and evaluation, audited beside others by Tony Marsland and Jacques Pitrat. || toc =Chess Programs= Along with Marc-François Baudot, Jean-Christophe Weill is co-author of the following chess programs :
 * Jean-Christophe Weill ||~  ||^   ||
 * Échec
 * Cumulus
 * Écume
 * Joker
 * Frenchess, with Jean-Luc Seret and Michel Gondran
 * Virtua Chess
 * Virtual Chess
 * Virtual Kasparov
