Hi, There are of course the normal cost values: unary, binary, ternary, linear, etc. The system picks the cheapest, however some cost values are treated alike. That is why there are no hard facts to be relied on.
But maybe you can give us an idea what you try to achieve?

As indicated by the documentation "The only hard fact you can rely on is that a propagator with a cost value using PropCost::HI is never given preference over a propagator with a cost value using PropCost::LO". For my particular problem however I'd need to weigh propagators quite differently, so they get executed almost sequentially, and simply saying LO or HI isn't enough. Does gecode offer another way to control the order of propagation?
