OptaPlanner stopped active development in 2023.
But it continues open source as Timefold Solver: solver.timefold.ai
The old website is now hosted here to help legacy users:
optaplanner.io
See the history for more information:

OptaPlanner is the most popular open source Constraint Solver in Maven Central (the 98 TerraByte Java and Kotlin repository) according to MvnRepository:

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!"

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...

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.

Video of my #DevoxxUK talk on Artificial Intelligence planning with @OptaPlanner (open source, Apache License, java).
It includes Live Coding, a scheduling puzzle and the minimal number of atoms in the known universe.

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.

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.

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.
