FORR

FORR is a satisficing architecture for learning and problem solving. Its premise is that agreement among reactivity, heuristics, planning, and search is a valid decision- making principle. A FORR-based program learns to specialize general domain expertise into problem-class specific expertise. An implemented FORR shell supports domain-specific development. FORR explores the relationship among reactivity, heuristics, and search. Applications include Hoyle for game playing, Ariadne for robot path finding and ACE for constraint satisfaction. Each of them has demonstrated substantial, learned expertise after relatively little training.

 

Current Work

- The integration of planning with high-level reasoning.

- Learning new heuristics.

- Autonomous restructuring of a decision hierarchy.

- Metaknowledge for heuristics.

- Multiagent solutions to multiple goal problems with (CD).
