Congratulations to former PSOR Lab member, Matthew Wilhelm for his recently published article in the Journal of Optimization Theory and Applications! This paper develops a new and improved approach for relaxing composite bilinear functions (i.e., f(x)=g(x)h(x)) that leads to a significant speedup in solution times for deterministic global optimization.
