Title: Answer Set Programming and Automatic Optimization Methods in its Realm

Abstract: Answer set programming is a popular constraint programming paradigm that has seen wide use across various industry applications. However, logic programs under answer set semantics sometimes require careful design and nontrivial expertise from a programmer to obtain satisfactory solving times. In order to reduce this burden on a software engineer we propose an automated rewriting technique for non-ground logic programs that we implement in a system PROJECTOR. We conduct rigorous experimental analysis, which shows that applying system PROJECTOR to a logic program can improve its performance, even after significant human-performed optimizations. This talk will present answer set programming, system PROJECTOR, the theory behind the system, and considered experimental analysis.
