Optimal flow analysis, prediction and application
Weili Zhang
This thesis employs statistical learning technique to analyze, predict and solve the fixed charge network flow (FCNF) problem, which is common encountered in many real-world networ…
Empirical analysis of metaheuristic search techniques for the parameterized dynamic slope scaling procedure
Weili Zhang, Charles D. Nicholson
The dynamic slope scaling procedure is an approximation method successfully which solves the fixed charge network flow (FCNF) problem by iteratively linearizing the fixed cost. The…
Objective Scaling Ensemble Approach for Integer Linear Programming
Weili Zhang, Charles Nicholson
The objective scaling ensemble approach is a novel two-phase heuristic for integer linear programming problems shown to be effective on a wide variety of integer linear programming…
