Explanation-based Constraint Programming A resource website ligne vide An introduction to explanations You will find here some basic information about explanations: a definition, possible uses, a presentation of explanation-based constraint programming, ... Implementations This section addresses some implementation issues on explanations: computation, quality of explanations, intrusive vs. non intrusive methods, ... This is also where you can find pointers on existing implementations including PaLM. Applications This is a repositery of descriptions of uses of explanations. Those applications are categorized: debugging (including PTIDEJ), illustrating constraint solving, solving dynamic problems, solving over-constrained systems, new search algorithms (including MAC-DBT and Path-Repair/decision-repair) ... Pointers Some further pointers for more detailed information: including discussion forums, web resources, interested people, a bibliography, related conferences, ...
