Solving ILP using OptaPlanner

[Inzemamul Haque]

Hi all!

I want to solve an ILP in Java. I was not able to find pure Java solvers. Therefore now looking for constraint solvers which can solve ILP. I have already tried ojAlgo which is not scalable as per our requirement. Then I came across OptaPlanner. But while going through the examples I couldn't understand how to use OptaPlanner to solve an ILP. I couldn't find any example which shows solving ILPs. 

Can someone help me by guiding me to some example in which OptaPlanner is used to solve an ILP?

Thanks and regards,

Inzemamul Haque.

Integer Linear Programming (ILP) is not a use case, it's a subset of constraint solving.
OptaPlanner does constraint solving, so it should be able to handle any ILP use case.

The CloudBalancing example is an ILP, take a look at that one. It has an quickstart in the docs.
The Tennis example is not an ILP, because it has a "fairness" constraint, which is non-linear.

With kind regards,
Geoffrey De Smet
