I am trying to solve vehicle routing problem in java and I am looking for libraries for the same. I did a POC using google or-tools and it seems to be solving all my use cases. I would like to know if anyone in the community has used OR-tools libraries in production and if yes, what are the problems I have to look out for ?
If not google or-tools, what are the other VRP java libraries you are using and how was your experience using them in production ? I am particularly interested in jsprit/ Optaplanner/or-tools etc., w.r.t ease of use, maintainability (when new constraints have to be added) and the performance in production.
