PPT-Finding Heuristics Using Abstraction

Kenny Denmark Jason Isenhower Ross Roessler Background A uses heuristics for efficient searching Initially heuristics provided by quotexpertquot Challenge is to have program create heuristics. brPage 3br Understanding Heuristics Symantecs Bloodhound Technology Introduction The word heuristic was initially coined by the Greeks its original form was heuriskein which meant to discover Today the term is used almost exclusively in computer sci of Synchronization.

Abstraction in the physical world Yaakov (J) Stein CTO, RAD There are 2 techniques frequently used to solve hard problems and which have been raised to an art in computer science The State of Techniques for Solving Large Imperfect-Information Games Tuomas Sandholm Professor Carnegie Mellon University Computer Science Department Also: Machine Learning Department Ph.D. Program in Algorithms, Way of classifying information from abstract (general) to concrete (specific) . . Level 4:. Abstractions. Level 3: . Noun Classes, broad group names with little specification. Level 2:. Noun Categories, more definite groups. Slide . 1. PHY Abstraction for MU-MIMO.
