I think there may be an error in the printing of constraints. I seem to be missing a bracket.
Below is code to generate one constraint (it is a small example I made to show this, my actual code is much more complex):
Store store = new Store();
BooleanVar cn = new BooleanVar(store, "CON");
BooleanVar a = new BooleanVar(store, "a");
BooleanVar b = new BooleanVar(store, "b");
BooleanVar c = new BooleanVar(store, "c");
ArrayList<PrimitiveConstraint> orConst = new ArrayList<PrimitiveConstraint>();
PrimitiveConstraint[] andConst = new PrimitiveConstraint[2];
andConst[0] = new XeqC(a, 1);
andConst[1] = new XeqC(b, 1);
orConst.add(new And(andConst));
orConst.add(new XeqC(c, 1));
store.impose(new IfThen(new XeqC(cn, 1), new Or(orConst)));
IntVar[] vars = {cn, a, b, c};
Search<IntVar> label = new DepthFirstSearch<IntVar>();
label.setPrintInfo(true);
SelectChoicePoint <IntVar> select = new SimpleSelect<IntVar>(vars, null,
new IndomainMin<IntVar>());
label.setSolutionListener(new PrintOutListener<IntVar>());
label.getSolutionListener().searchAll(true);
boolean result = label.labeling(store, select);
if (result) {
System.out.println("Yes");
} else {
System.out.println("No solution.");
}

Constraint:
IfThen1 : IfThen(
XeqC4 : XeqC(CON::{0..1}, 1 ),
Or1 : Or( And1 : And(XeqC1 : XeqC(a::{0..1}, 1 )XeqC2 : XeqC(b::{0..1}, 1 ),, XeqC3 : XeqC(c::{0..1}, 1 )), )
when I think it should be:
IfThen1 : IfThen(
XeqC4 : XeqC(CON::{0..1}, 1 ),
Or1 : Or( And1 : And(XeqC1 : XeqC(a::{0..1}, 1 )XeqC2 : XeqC(b::{0..1}, 1 )),, XeqC3 : XeqC(c::{0..1}, 1 )), )
if I have them both Or instead I get:
IfThen1 : IfThen(
XeqC4 : XeqC(CON::{0..1}, 1 ),
Or2 : Or( Or1 : Or( XeqC1 : XeqC(a::{0..1}, 1 ), XeqC2 : XeqC(b::{0..1}, 1 )),, XeqC3 : XeqC(c::{0..1}, 1 )), )
Can you confirm that this is a bug with the printing? When I generate all solutions, they appear to be correct.
Thanks!
Yes, you are right. There is a bug in method toString in And class (constraint).
