pm4py.algo.conformance.alignments.process_tree.variants.search_graph_pt.align_variant(variant, tree_leaf_set, pt)[source]
pm4py.algo.conformance.alignments.process_tree.variants.search_graph_pt.apply(obj: Union[pm4py.objects.log.obj.EventLog, pm4py.objects.log.obj.Trace], pt: pm4py.objects.process_tree.obj.ProcessTree, parameters: Optional[Dict[Any, Any]] = None) → Union[Dict[str, Any], List[Dict[str, Any]]][source]

Returns alignments for a process tree

Parameters:
  • obj – Event log or trace (a conversion is done if necessary)
  • pt – Process tree
  • parameters – Parameters of the algorithm
Returns:

Alignments
Return type:

alignments
pm4py.algo.conformance.alignments.process_tree.variants.search_graph_pt.apply_from_variants_list(var_list, tree, parameters=None)[source]

Apply the alignments from the specification of a list of variants in the log

Parameters:
  • var_list – List of variants (for each item, the first entry is the variant itself, the second entry may be the number of cases)
  • tree – Process tree
  • parameters – Parameters of the algorithm
Returns:

Dictionary that assigns to each variant its alignment
Return type:

dictio_alignments
pm4py.algo.conformance.alignments.process_tree.variants.search_graph_pt.apply_multiprocessing(obj: Union[pm4py.objects.log.obj.EventLog, pm4py.objects.log.obj.Trace], pt: pm4py.objects.process_tree.obj.ProcessTree, parameters: Optional[Dict[Any, Any]] = None) → Union[Dict[str, Any], List[Dict[str, Any]]][source]

Returns alignments for a process tree (using the multiprocessing package to distribute the workload among different cores)

Parameters:
  • obj – Event log or trace (a conversion is done if necessary)
  • pt – Process tree
  • parameters – Parameters of the algorithm
Returns:

Alignments
Return type:
