Load balance flight duration

I want to know in the flightcrewscheduling prolem ,how to change this soft contraint:Load balance flight duration total per employee,because
I want to balance part of employee's flight duration,not all the employee。How to do it?
Need your help,thank you.

FlightCrewSolution-null

Hello，now I can get a result quickly.Look the result:
GL0537→LSS0653, LSS0653→FU0721, FU0721→LSX0754, LSX0754→NH0818, NH0818→LSS0849, LSS0849→FU0918, FU0918→LSX0948, LSX0948→NH1013, NH1013→LH1044

But I want to transfer betweent two flights has some time space >=15 minutes,like:
GL0537→LSS0653, LSS0709→FU0738,

So I change this function below,but it work a long time and get no solution(FlightCrewSolution-null).What can I do?

    public long countInvalidConnections() {
        // TODO Cache this to improve example performance.
        // Especially useful for Constraint Streams, by which this is called multiple times per Employee.
        long count = 0L;
        FlightAssignment previousAssignment = null;
        for (FlightAssignment assignment : flightAssignmentSet) {
            if (previousAssignment != null
                    && (previousAssignment.getFlight().getArrivalAirport() != assignment.getFlight().getDepartureAirport()||assignment.getFlight().getDepartureUTCDateTime().compareTo(previousAssignment.getFlight().getArrivalUTCDateTime())<15)) {
                count++;
            }
            previousAssignment = assignment;
        }
        return count;
    }

HTTP Request to /timeTable failed

Hi,

I had already reported this issue (see 109) and it was closed as resolved, but I'm arfaid I must tell you, it is not.
The behaviour stayed exactly the same as before.

My setup and steps have stayed the same.
(Appart from using the lates sources from git - also I'm not sure if anything appart from dependencies has actually changed)

Setup:
Win10,
eclipse 4.19.0,
gradle 6.8

I went with 'live coding' and started the app with the gradle command as suggested in the readme.
When refreshing the browser the initial call to 'getTimeTable()' crashes.

It seems like a Path is created from an URI causing the error.
Please let me know, if I am doing anthing wrong, or if you have any further questions.

Compilation error

Hi,
I'm trying to build and run the project, but I've got the following error :

[ERROR] No plugin found for prefix 'quarkus' in the current project and in the plugin groups

I could not find any help on the subject, would you have any hint ?

Thx

HTTP Request to /timeTable failed

Hi,

I tried to get the 'quarkus-school-timetabling' example running.

Setup:
Win10,
eclipse 4.19.0,
gradle 6.8

I went with 'live coding' and started the app with the gradle command as suggested in the readme.
When refreshing the browser the initial call to 'getTimeTable()' crashes.

I updated to the lates Quarkus, but the behaviour also appears with the version originaly used.

It seems like a Path is created from an URI causing the error. But I have no idea where the String comes from.
Please let me know, if I am doing anthing wrong, or if you have any further questions.

how to implement hard constraint

hi,

I just discovered and started testing your tool (running on linux mint, e.g. with runQuickstarts.sh )

• the constraint I need to implement is the fixed N of weekly hours per subject, per classroom -- how should I proceed?

• also: I do not understand why only 1 room and only few time slots are filled? do I have to create as many 'lesson' block as time-slots? (related to 1st)

thanks

should I rather ask on https://groups.google.com/g/optaplanner-dev ?

Caused by: java.lang.IllegalStateException:

When I construct a flight crew scheduling problem ,it caused such problem:

Caused by: java.lang.IllegalStateException: The entity (AB071@2018-01-01-0) has a variable (employee) with value (Chad Q. Green) which has a sourceVariableName variable (flightAssignmentSet) with a value ([AB003@2018-01-01-0, AB019@2018-01-01-0, AB047@2018-01-01-0, AB070@2018-01-01-0]) which already contained the entity (AB071@2018-01-01-0).
Verify the consistency of your input problem for that bi-directional relationship.

How to handle this problem?Hope for your answer.

Refocus examples on OptaPlanner by bringing back the good old *App

The new examples put too much focus on system integration with quarkus. In fact, they hide the underlying optaplanner concepts to an extent that new users may not understand the API. Or are simply overwhelmed with quarkus complexity, and move on to OR tooling that has a lower entry barrier in its introductory examples.

Don't get me wrong, the demos and their great web interfaces are just awesome. However, they imho don't educate on how to use optaplanner in the same simplistic way the old demos did. They are more integration examples than quickstarts, which I'd expect to also quick to understand and not just quick to run.

Most importantly quarkus quickstarts lack a solverconfig, which accordingly to the docs (https://docs.optaplanner.org/8.14.0.Final/optaplanner-docs/html_single/index.html#solverConfigurationByJavaAPI) is the heart of an optaplanner solution. The config has somehow has been engineered away, which dramatically impedes the learning experience.

The demos should include an "App" as done in the non-quarkus demos. E.g. TimeTableApp is so much more instructive on how to use optaplanner: It shows how to bind all entity definitions, constraints and the solution classes into a solver-config, builds a solver, creates a dummy problem, and solves it. The code explains itself.

In contrast, the call-center demo does not even seem to have an application entrypoint. The quarkus examples are just providing loose uncoupled definitions which are magically bound behind the scenes into an actual application driven by annotations the reader may not be familiar with (or may not care about). And it seems that quarkus quickstarts are using methods beyond annotations to glue the applications together: org.acme.callcenter.solver.CallCenterConstraintsProvider is not annotated and is not referenced at all in the entire repo except in the tests, so it leaves the reader in the dark how it may be discovered to run the call center.

I hope was not too negative here. But I could imagine that other users may struggle as well.
