The solving will take as long as specified in the solverConfig.

<solver>
  ...
  <termination>
    <!-- Terminate after 10 seconds, unless it's not feasible by then yet -->
    <terminationCompositionStyle>AND</terminationCompositionStyle>
    <secondsSpentLimit>10</secondsSpentLimit>
    <bestScoreLimit>-1hard/0soft</bestScoreLimit>
  </termination>
  ...
<solver>

NOTE While the Solver is solving, it will effectively hog the camel thread. Future improvements might include solving in a separate thread:

  • Asynchronous solving: 1 request starts the solving and registers a callback. When the Solver terminates, the best Solution is returned through the callback.

  • 2 phase request solving: 1 request starts the solving on a separate thread. Another request (with an id to the first request) terminates the Solver with Solver.terminateEarly() and returns the best Solution.

Samples

Solve an planning problem that's on the ActiveMQ queue with OptaPlanner:

from("activemq:My.Queue").
  .to("optaplanner:/org/foo/barSolverConfig.xml");

Expose OptaPlanner as a REST service:

from("cxfrs:bean:rsServer?bindingStyle=SimpleConsumer")
  .to("optaplanner:/org/foo/barSolverConfig.xml");
