New algorithm tackles complex fixed-charge network flow problems

Researchers have developed a new algorithm for the fixed-charge network flow problem (FCNFP), a complex optimization challenge that combines continuous flow allocation with discrete decisions. This novel approach, based on an iteratively reweighted least-squares (IRLS) framework, smooths the objective function and solves a series of weighted quadratic flow subproblems. Computational experiments on a large dataset of benchmark instances demonstrated that the proposed method achieves superior objective quality compared to other scalable FCNFP algorithms, with a mean gap of 1.316% to a time-limited mixed-integer linear programming reference.
