Instance-Specific Algorithm Configuration

Dr. Yuri Malitsky received his PhD from Brown University in 2012 for his work on the Instance-Specific Algorithm Configuration (ISAC) approach. He was a postdoc in the Cork Constraint Computation Centre from 2012 to 2014. He is now a postdoc at the IBM Thomas J. Watson Research Center, working on problems in machine learning, combinatorial optimization, data mining, and data analytics. Dr. Malitsky's research focuses on applying machine learning techniques to improve the performance of combinatorial optimization and constraint satisfaction solvers. In particular, his work centers around automated algorithm configuration, algorithm portfolios, algorithm scheduling, and adaptive search strategies, aiming to develop the mechanisms to determine the structures of problems and their association with the behaviors of different solvers, and to develop methodologies that automatically adapt existing tools to the instances they will be evaluated on.
