2020 AIJ Classic Paper Award

Temporal Constraint Networks

R Dechter, I Meiri, J Pearl - Artificial intelligence, 1991


This seminal paper introduced the temporal constraint satisfaction problem (TCSP), for quantitative temporal reasoning. The TCSP, and the polytime solvable special case of simple (non-disjunctive) temporal problems, have gained widespread use in planning & scheduling and other applications. The simple and elegant problem formulation of this paper also inspired subsequent work on temporal reasoning with temporal uncertainty, preferences, and other extensions.

2020 AIJ Prominent Paper Award

Conflict-based search for optimal multi-agent pathfinding

G Sharon, R Stern, A Felner, N Sturtevant - Artificial intelligence, 2015


This paper introduced an elegant and novel formalisation of the multi-agent pathfinding problem, based on the resolution of conflicts and on searching a conflict tree. Upon its publication, this work substantially improved state-of-the art performance. In the years since, the paper has become a reference in the area, with many subsequent variations, extensions and generalisations. Today, these contributions are being successfully applied to solving a broad range of important industrial applications including aircraft towing, automated warehouses, office robots and video games.
