WebThe TSPTW in or-tools — or-tools User's Manual. 9.9. The TSPTW in or-tools. In this section, we try to solve the TSPTW Problem. First, we use Dimension s to model the time windows and the default routing strategy. Then, we use a basic heuristic to create a starting solution for the Local Search. 9.9.1. WebAbstract. Constraint Programming (CP) has been successfully applied to several combinatorial optimization problems. One of its advantages is the availability of complex global constraints performing efficient propagation and interacting with each other through shared variables. However, CP techniques have shown their limitations in dealing with ...
