= Call center real-time scheduling with setup avoidance
Schedule incoming calls to employees matching skills and availability.
Created by adopting the great example from https://github.com/kiegroup/optaplanner-quickstarts/tree/stable/use-cases/call-center
Discussed in https://groups.google.com/g/optaplanner-dev/c/wnalNxLT3Jw
Changes compared to the original are
* Simplified `Call`s to have just one required skill
* If 2 subsequent calls have a different required skill, a setup cost occurs (expressed via a constraint).
The current implementation imposes a setup cost only. This is sufficient to avoid setup via constraint. It would be also very easy to change `getDurationTillPickUp` to model a setup-time instead.
TIP: In addition to the quarkus mode, here we also include `org.acme.callcenter.CallCenterApp` to run the solver without any interface.

== Run the application with live coding
. Git clone the optaplanner-quickstarts repo:
+
[source, shell]
----
$ git clone https://github.com/kiegroup/optaplanner-quickstarts.git
...
$ cd optaplanner-quickstarts/use-cases/call-center
----
. Start the application:
+
[source, shell]
----
$ mvn quarkus:dev
----
. Visit http://localhost:8080 in your browser.
. Click on the *Solve* button.
Then try _live coding_:
. Make some changes in the source code.
. Refresh your browser (F5).
Notice that those changes are immediately in effect.
== Package and run the application
When you're done iterating in `quarkus:dev` mode, run the application as a conventional jar file.
. Compile it:
+
[source, shell]
----
$ mvn package
----
. Run it:
+
[source, shell]
----
$ java -jar ./target/quarkus-app/quarkus-run.jar
----
+
[NOTE]
====
To run it on port 8081 instead, add `-Dquarkus.http.port=8081`.
====
. Visit http://localhost:8080 in your browser.
== Run a native executable
. https://quarkus.io/guides/building-native-image#configuring-graalvm[Install GraalVM and gu install the native-image tool]
. Compile it natively:
+
[source, shell]
----
$ mvn package -Dnative -DskipTests
----
. Run the native executable:
+
[source, shell]
----
$ ./target/*-runner
----
. Visit http://localhost:8080 in your browser.
