OptaPlanner: changeMoveSelector

At first I implemented a SolverConfig.xml with a changeMoveSelector like this:

<changeMoveSelector>
            <entitySelector>
                <entityClass>Project</entityClass>
            </entitySelector>
            <valueSelector>
                <variableName>developer</variableName>
            </valueSelector>
</changeMoveSelector>

After 10 seconds of optimization I got the following result: -388hard/-65165soft

After that I uncommented the changeMoveSelector and after 10 seconds of optimization I got the following (better!) result: -350hard/-64713soft

How does OptaPlanner "moves", when there is no changeMoveSelector stated?

If no move selectors are defined, Local Search defaults to a union of change and swap moves - which explains your better result. It's in the docs IIRC.
