value of a tech = benefits/cost if cost=0, technology invalable. how to make invaluable agents? what is an agent: newell. choices. what do agents control? models. models have keys proposals: 1) make "choice" an abstract data type 2) instrument a model by swapping standard variables with choices 3) monte carlo the model, use data mining to find good choices reality check: good is domain-specific - class level unit tests - path level ---------- can use "cache" for fuzzy logic networks can use "cahces" to summarize results and replay them for (e.g. scoring pruposes knowledge acuquion: find critical thresholds where behavior changes certification: ceritication envelipes ---------- need to specifcy goals the query problem access-oriented logics R++ augment R++ with unviersal relations - compute nonambogiys isand roudn the local space need a language to define "things" and "roles" between things need a behavior language: - state chart - rules - am i doing aspects? goals: - association rules - local test agents - runtime monitors - authored manually - authored via bucchi - access rules
