I recently started looking into Google-OR tools. However, I do not see mathematical formulations of any of the problems the OR-tools can solve. Without looking at the model (set, objective, constraints, etc), it is hard for me to understand the problem. Does anyone know where I can find them? If you used it for your work, how did you use the tools?
This page includes all the codes for the instances that are written to be used in the Google-Or tool. Variety of languages such as C++, Python, DotNet and Java are used to write the codes and solve the instances using Google-OR tool.
