I am the lead for OptaPlanner
(java, open source) and I work for Red Hat.
OptaPlanner optimizes business resource usage. Every organization faces planning problems: provide products or
services with a limited set of constrained
resources (employees, assets, time and money). OptaPlanner optimizes such
planning to do more business with less resources.
OptaPlanner is a lightweight, embeddable planning engine written in Java™. It helps normal Java™ programmers solve
constraint satisfaction problems efficiently. Under the hood, it combines optimization heuristics and metaheuristics
with very efficient score calculation.OptaPlanner is open source software, released under the Apache Software License. It is 100% pure
Java™, runs on any JVM and is available in the Maven Central Repository too.
