All the moves in each neighborhood define a complete sequence of resource constraints on each resource. By definition, this must satisfy the unary capacity resource constraints. Furthermore, since each move is completely defined by the neighborhood object, there is no benefit from extra constraint propagation. We can therefore save time by ignoring the resource capacity constraints without losing soundness.

  IloSchedulerEnv schedEnv(env);
  schedEnv.getResourceParam().ignoreCapacityConstraints();
