Release 6.13.98 of DiSCover

Today, version 6.13.98 of the DiSCover package has been released. This release comes with an improved “Xcavate Petri net” plug-in that allows the user to also select the classifier to use.

The user can now select the classifier to use.
Net excavated when selecting Event Name as the classifier.
Net excavated when selecting MXML Legacy Classifier as the classifier.
Net excavated when selecting Resource as classifier.

The release also includes the following updates:

  • Improved the handling of WF-nets. If a WF-net is preferred and a WF-net is discovered during the excavation, the best discovered WF-net will be returned. Otherwise, the best discovered net (either WF-net or not) will be returned.
  • The check whether or not a net is a WF-net is now a dedicated check. In previous releases, Woflan was used for this, but Woflan computes a shortest path for every node to every node, which is overkill.
  • Alignments are only computed for nets that have at most the provided maximal number of transitions. As a result, fitness and precision are only computed for those nets. The effect of setting this maximum to 0 is that only simplicity will be used to rank the discovered nets.
  • The construction of the maximal activity set has been improved. As a result, it will typically take much less memory.
