<pre>Hi guys!
I'm using drools-planner-*5.4.0.CR1*...
Let's say I have some solution(NOT FINAL BEST SOLUTION) which done by human
manually and I want get list of broken contraints for that solution, I've
tried
this.scoreDirector.setWorkingSolution(someSolution);
this.scoreDirector.calculateScore();

Something like that should work. For the exact correct usage, see
the new section for the 5.4.0.Final manual:<br>
<a href="https://hudson.jboss.org/hudson/view/Drools%20jBPM/job/drools-planner/lastSuccessfulBuild/artifact/drools-planner-docs/target/docbook/publish/en-US/html_single/index.html#d0e3786" target="_blank">https://hudson.jboss.org/hudson/view/Drools%20jBPM/job/drools-planner/lastSuccessfulBuild/artifact/drools-planner-docs/target/docbook/publish/en-US/html_single/index.html#d0e3786</a><br>
It should never return null. I do in the examples all the time.<br>
<br>
There is a point though, that the code above still requires the
creation of a Solver (but it doesn't you to actually run it):<br>
<pre><a><span>ScoreDirectorFactory</span><span> scoreDirectorFactory </span><span>=</span><span> solverFactory.buildSolver()</span><span>.</span><span>getScoreDirectorFactory</span><span>();</span>
<span>ScoreDirector</span><span> guiScoreDirector </span><span>=</span><span> scoreDirectorFactory</span><span>.</span><span>buildScoreDirector</span><span>();
</span></a><a><span>guiScoreDirector</span><span>.</span><span>setWorkingSolution</span><span>(</span><span>solution</span><span>);</span>
<span>Score</span><span> score </span><span>=</span><span> guiScoreDirector</span><span>.</span><span>calculateScore</span><span>();</span></a><a>
</a></pre>
Feel free to make a jira if you agree that it shouldn't be needed to
do a ".buildSolver()" in that code.<div class="im"><br>

<blockquote type="cite">
<pre>it returns *null* since it isn't connected with Solver
then I've tried using Solver with
<termination><maximumStepCount>0</maximumStepCount></termination>:
this.scoreDirector.setWorkingSolution(someSolution);
this.solver.setPlanningProblem(this.scoreDirector.getWorkingSolution());
this.solver.solve();
this.scoreDirector.setWorkingSolution(this.solver.getBestSolution());
this.scoreDirector.calculateScore();
then it shows *java.lang.UnsupportedOperationException* because there is no
best solution in Solver
java.lang.UnsupportedOperationException: StepCountTermination can only be
used for phase termination.

how can implement this task? or I have to implement setBestSolution in
Solver, i think this is bad idea...

bad idea indeed<div class="im"><br>
