OptaPlanner is End Of Life as of 30 May 2024. Its creators forked and continue it as Timefold Solver.
Joined March 2011
OptaPlanner is the most popular open source Constraint Solver in Maven Central (the 98 TerraByte Java and Kotlin repository) according to MvnRepository: https://t.co/LSD3ORUymY

Feedback from a user about CS: "I had to convert around 30 rules written in DRL to ConstraintStreams. After struggling at the beginning I started to like it more and more. At the end I really liked it. Thanks a lot for this awesome work!" Migration guide:

We'll publish the Devoxx Belgium schedule later this week. Basically @OptaPlanner will generate the schedule based on the received speakers availability and other soft/hard constraints we have defined. More details in this related Devoxx talk... https://t.co/yYFzR9yA1O

How hard can it be to write a program to solve a simple lesson scheduling problem? Harder than you think. Watch @dupliaka and me try it with a Greedy algorithm, a Brute Force algorithm and an advanced Metaheuristic at @DevoxxPL. Full video: https://t.co/90xWE0wtcP

OptaPlanner made it on @baeldung 's #AI in @Java list. Is planning optimization (vehicle routing, employee rostering, maintenance scheduling, ...) going mainstream?

Do you want to host your @OptaPlanner application in the cloud? Just import the Git url in @OpenShift (open source container platform build on Kubernetes). This already works for all OptaPlanner's use case quickstarts. Give it a try. https://t.co/67pEXrEtJK

For full clarity: One quickstart does have log4j-api and its slf4j bridge in their dependency tree transitively, but neither of these jars are vulnerable to Log4jShell, because they don't contain the Log4J implementation. So it's all safe.

OptaPlanner does not depend on #Log4J. It depends on SLF4J (the simple logging facade), so it brings in no actual logging implementation. The OptaPlanner examples/quickstarts typically use Logback as the logging impl. SLF4J/Logback has no known CVEs. None of them use Log4J.

@GeoffreyDeSmet @McCrews Only schools. At the start of school year/semester, each school requested swimming lanes for all classes. Manual planning could no longer fulfill all requests. Optaplanner solution got swim lane occupation down to 60~70%.

Artificial Intelligence with #Quarkus and #OptaPlanner for @DevoxxUA To assign 400 lessons to 400 slots (40 timeslots across 10 rooms) there are 10^1080 combinations. A 99% improvement is a rounding error. https://t.co/YbvcQQ5j2p
