There is one indexing error related to them in the code. You have the Miller-Tucker-Zemlin constraints in your code, commented out. Here is the mod and dat file for the vehicle routing problem. Hope to receive replies from expert in related field of study. Can I have some suggestion from the expert here in providing a guidance and references for me. The version of CPLEX that I am using currently is version 20.1.0.0. I do encounter a problem which is regarding the code for subtour elimination constraints. Recently i am working on the vehicle routing problem. However, if you think of migrating to C/C++, you could try to integrate pre-existing C++ code that implements different subtour breaking constraints for the VRP efficiently. I am not aware of any pre-existing libraries that you can import into OPL CPLEX IDE. Subject: Subtour Elimination Constraints for Vehicle Routing Problem
