Extreme-Scale Evolutionary Optimization: A Case Study on a Billion-Variable Resource Allocation Problem
Kalyanmoy Deb
Michigan State University

Talk Abstract: Optimization methods and practices are around for more than 50 years, but they are still criticized for their "curse of dimensionality". In this talk, we shall look at a specific large-dimensional integer-valued resource allocation problem class from practice and review the performance of well-known softwares, such as IBM's CPLEX, on the problem. Thereafter, we shall present a population-based heuristic search algorithm that has the ability to recombine short-sized building blocks, despite having overlapping variable linkage, to form larger-sized building blocks. The process is eventually able to solve a billion-variable version of the problem to near-optimality in a polynomial computational time, making the application one of the largest size optimization problems ever solved.
