                                   org.processmining.models.graphbased.directed.petrinet.PetrinetGraph model)

Description copied from class: OptimalMiner

Computes the distance between a log and a model Subclasses need to implement this according to their model type. Ideally, this is a fast step.

Specified by:

computeDistance in class OptimalMiner<org.processmining.models.graphbased.directed.petrinet.PetrinetGraph>

Parameters:

log - the log to compare with the model

model - the model to compare with the log

Returns:

Distance

Description copied from class: LocalSearchMiner

we assume that the alignment guides us in changing the graph.

Specified by:
