Here, you have to use the "copy constructor" for test and test_mut:
public GecodeTest(Boolean share, GecodeTest gecodeTest) {
super(share, gecodeTest);
test = new VarArray<IntVar>(this, share, gecodeTest.test);
test_mut = new VarArray<IntVar>(this, share, gecodeTest.test_mut);
}
Otherwise, every solution will reference the variables in the original
space, and that's what you print.
Cheers,
Guido
