Well, after couple of hours in front of an old CRT I haven't
considered my perceptions reliable.

I prefer messing around with my code, than with gecode's, so
I use a workaround for now (the constants are 0 and this
avoids the impact of sign*-c):
=-=-=-=-=-=Begin
IntVar
get_variable_difference(Solver *space, IntVar& var1, int var2){
- return abs(space, post(space, var1 - var2, ICL_DOM), ICL_DOM);
+ IntVar tmp(space, var2, var2);
+ return abs(space, post(space, var1 - tmp, ICL_DOM), ICL_DOM);
}
=-=-=-=-=-=End
Could using a temp IntVar (and as consequence one Term more
inside the LinExpr, I guess) be a considerable performance
issue?
cheers
