Webheuristics: constraint-handling in evolutionary algorithms. In this paper, we will use a GA as a numerical tool to propose a constraint-handling technique that eliminates the use of … WebMay 7, 2014 · Hard constraints stand out because they can break relationships. An activity that has a Mandatory Start or Finish date becomes fixed to that date. Relationships to that activity are ignored – the activity will not move even if its predecessors push it out. All of P6’s other constraints are considered soft constraints.
