timefold-solver

Why we included this project

Teams building planning software in Java or Kotlin will find this constraint solver a solid first choice. It tackles the classic hard optimization problems, vehicle routing, employee rostering, task assignment, and maintenance and school timetabling, by letting you describe the constraints and letting the engine search for a good solution. Because it is a fork of OptaPlanner by the original team, it brings years of production hardening and a large, active community, which matters when you are betting a scheduling feature on a library. You model your problem in plain Java or Kotlin, embed the solver in your existing application, and get local search and other heuristics out of the box instead of writing them yourself.
