CS Colloquium: Satish Kumar Thittamaranahalli (USC) – The Constraint Composite Graph and Its Applications

Speaker: Satish Kumar Thittamaranahalli, USC Information Sciences Institute

Talk Title: The Constraint Composite Graph and Its Applications

Series: Computer Science Colloquium

Abstract: The weighted constraint satisfaction problem (WCSP) is a fundamental combinatorial problem with applications in such diverse areas as artificial intelligence, statistical physics, computer vision, and information theory. In this talk, I will present new methods for efficiently solving the WCSP. Central to these methods is the idea of the constraint composite graph (CCG). The CCG provides a unifying computational framework for simultaneously exploiting the structure of the variable-interactions in a given WCSP as well as the structure of the weighted constraints in it. I will present some important applications of the idea of the CCG in kernelization of combinatorial problems, the revival of message passing algorithms, and in other domains (if time permits).

This lecture satisfies requirements for CSCI 591: Research Colloquium. Please note, due to limited capacity in OHE 100D, seats will be first come first serve.
