Relevance analysis for a task.

Parameters:
  • task (GStripsProblem) – the StripsTask to be analyzed.

  • relaxed_relevance (bool) – whether to use relaxed relevance analysis. If this is set to False, we will not drop functions that are “implicitly” used by

  • forward (bool) – whether to run the forward pruning (forward reachability checking).
