The algorithm described here, called OptQuest/NLP or OQNLP, is a heuristic designed to find global optima for pure and mixed integer nonlinear problems with many constraints and variables, where all problem functions are differentiable with respect to the continuous variables. It uses OptQuest,...

The minimum routing and wavelength assignment (min-RWA) problem is a classic and challenging NP-hard combinatorial optimization problem which aims to reduce the required wavelengths in wavelength-division multiplexing optical networks. In order to tackle this problem, we present a...
