Tutorial Presentations at the Twelfth International Conference on Principles of Knowledge Representation and Reasoning

In particular, I will explain how the complexity scheduling, planning, graph problems, among others. The landscape differs for traditional reasoning and for query most well-known constraint satisfaction problem is propositional answering, and take a brief look at computational complexity satisfiability SAT. Of particular recent interest is satisfiability issues raised by implementations of DL query answering modulo theories (SMT), where the interpretation based on standard relational database systems. Throughout of some symbols is constrained by a background theory. For the tutorial, connections to the W3C-standard OWL are example, the theory of arithmetic restricts the interpretation drawn whenever possible. of symbols such as:,, 0, and 1. SMT draws on the most prolific problems in the past century What If You Wanted Someone (Else) to Use This?
