Rename constraint_relaxation to violation_relaxation

Tjerk Vreeken requested to merge rename-constraint-epsilon-relaxation into master

The "constraint_relaxation" name was confusing, as the relaxation was only indirectly applied to the eventual hard constraint (i.e. it was scaled by the goal's function nominal as well). The term violation_relaxation much better describes how this relaxation is applied.

-- NOTE A previous recommendation was epsilon_relaxation. The name epsilon is however not used in the docs at all, so that would have been confusing. The docs talk about a "violation variable" and "the violation", which was the deciding factor for picking "violation_relaxation" over "epsilon_relaxation".

The renaming to something more appropriate is one thing, but it's also about opening up the name constraint_relaxation for future use. Then it will be directly applied to the constraints that are generated, without any scaling.

  • Rename epsilon_relaxation to violation_relaxation.
