What is the convention for determining if a problem or constraint that wants to be applied, should be a hard or soft constraint. After that choosing between route or activity constraint? I’ve tried reading the new docs but it’s incomplete and the examples don’t shed much light on this.
Whereas hard constraints must be met and cannot be broken, soft constraints are always fulfilled but uses penalties to express “good” and “bad” insertions.
Regarding route vs. activity constraints, take hard constraint for example:
The activity and route constraints is clearer, thanks.
The hard vs soft, other than the method of determining if they are fulfilled, sound too similar in their definitions. In what cases is it more beneficial one over the other?
