class pm4py.algo.analysis.extended_marking_equation.algorithm.Variants(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)[source]#

Bases: Enum

CLASSIC = <module 'pm4py.algo.analysis.extended_marking_equation.variants.classic' from 'C:\\Users\\berti\\pm4py-core\\pm4py\\algo\\analysis\\extended_marking_equation\\variants\\classic.py'>#

pm4py.algo.analysis.extended_marking_equation.algorithm.build(trace: Trace, sync_net: PetriNet, sync_im: Marking, sync_fm: Marking, variant=Variants.CLASSIC, parameters: Dict[Any, Any] | None = None) → Any[source]#

Builds the extended marking equation out of a trace and a synchronous product net

Parameters#

trace

Trace

sync_net

Synchronous product net

sync_im

Initial marking (of sync net)

sync_fm

Final marking (of sync net)

variant

Variant of the algorithm to use, possible values: - Variants.CLASSIC

parameters

Parameters of the algorithm, including: - Parameters.CASE_ID_KEY => attribute to use as case identifier - Parameters.ACTIVITY_KEY => attribute to use as activity - Parameters.COSTS => (if provided) the cost function (otherwise the default cost function is applied) - Parameters.SPLIT_IDX => (if provided) the split points as indices of elements of the trace

(e.g. for [“A”, “B”, “C”, “D”, “E”], specifying [1,3] as split points means splitting at “B” and “D”). If not provided, some split points at uniform distances are found.

Parameters.MAX_K_VALUE => the maximum number of split points that is allowed (trim the specified indexes
if necessary).
Parameters.INCIDENCE_MATRIX => (if provided) the incidence matrix associated to the sync product net
Parameters.A => (if provided) the A numpy matrix of the incidence matrix
Parameters.CONSUMPTION_MATRIX => (if provided) the consumption matrix associated to the sync product net
Parameters.C => (if provided) the C numpy matrix of the consumption matrix
Parameters.FULL_BOOTSTRAP_REQUIRED => The preset/postset of places/transitions need to be inserted

pm4py.algo.analysis.extended_marking_equation.algorithm.get_h_value(solver: Any, variant=Variants.CLASSIC, parameters: Dict[Any, Any] | None = None) → int[source]#

Gets the heuristics value from the extended marking equation

Parameters#

solver: Extended marking equation solver (class in this file)
variant: Variant of the algorithm to use, possible values: - Variants.CLASSIC
parameters: Possible parameters of the algorithm
