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...

Watch the latest episode of #CommunityCentral, where @dupliaka explains the power and benefits of @optaplanner https://t.co/SPmdca7mo1

[Geoffrey De Smet @GeoffreyDeSmet]

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.

Going to @devnexus in Atlanta next week?
Don't miss Jason Porter's (@lightguardjp) talk about AI planning and schedule optimization with @OptaPlanner.

OptaPlanner made it on @baeldung 's #AI in @Java list. Is planning optimization (vehicle routing, employee rostering, maintenance scheduling, ...) going mainstream? https://t.co/HMCV2cL7bi

[Geoffrey De Smet @GeoffreyDeSmet]

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 @optaplanner]

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 @optaplanner]

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.

Got an organizational problem, with constraints that can’t budge? #OptaPlanner uses #AI and algorithms to find the best solution to your challenge. #RedHat guest @donato_m tells us all the ways OptaPlanner can be utilized in this episode of #DeployFriday https://t.co/LD1U1lMm1O
