Reasoning about multi-agents systems at the knowledge level allows us to abstract away from many concrete details of the systems we are considering. Fagin et al. introduced two notions to facilitate designing and reasoning about systems in terms of knowledge. The first notion is that of knowledge-basedprograms. Knowledge-based programs are defined as syntactic objects: programs with tests for k...

Specifically, it was hypothesized that community integration contributes to physical, psychological, social, and environmental QOL. Out of 240 individuals from the mailing list of the Adapti...

We introduce Probabilistic Knowledge-Based Programs (PKBPs), a new, compact representation of policies for factored partially observable Markov decision processes. PKBPs use branching conditions such as if the probability of φ is larger than p, and many more. While similar in spirit to valuebased policies, PKBPs leverage the factored representation for more compactness. They also cope with more...

Prevention programs for adolescents and their families are designed to reduce youth problems and promote positive development by addressing assets and risk and protective factors at the family level. A growing body of research conducted over the past 30 years on the efficacy of family-based prevention models provides increasing support for the value of this approach. The literature on evidence-...
