Graph Generation: A New Approach to Solving Expanded Linear Programming Relaxations
Julian Yarkony, Naveed Haghani, Amelia Regan
In this article we introduce Graph Generation, an enhanced Column Generation (CG) algorithm for solving expanded linear programming relaxations of mixed integer linear programs. To…
Detour Dual Optimal Inequalities for Column Generation with Application to Routing and Location
Julian Yarkony, Naveed Haghani, Amelia Regan
We consider the problem of accelerating column generation (CG) for logistics optimization problems using vehicle routing as an example. Without loss of generality, we focus on the…
Multi-Robot Routing with Time Windows: A Column Generation Approach
Naveed Haghani, Jiaoyang Li, Sven Koenig +4
Robots performing tasks in warehouses provide the first example of wide-spread adoption of autonomous vehicles in transportation and logistics. The efficiency of these operations,…
