Parameters:

numberOfDrifts: - number of drifts (changes in behavior). Gradual/Momentary drifts are counted as one, but algorithms will probably detect two drift points: when the drift begins and when it ends

durationOfDriftPeriod: - Distribution used to generate the duration of the drifting period (def 1 day)

durationOfStablePeriod: - Distribution used to generate the duration of a stable period (with no drifts) (def 6 days)

samplingProbEvenPeriods: - probability of sampling from the base petrinet in a stable period (even: 0, 2, 4)

samplingProbOddPeriods: - probability of sampling from the base petrinet in a stable period (odd: 1, 3, 5).

driftType - type of drift to be injected: Sudden, Gradual or Momentary (Momentary drift is reverted back without a stable period).

driftTransitionFunction - The function to estimate the probability distributions of sampling from the petrinets during the drift. could be Linear or Exponential

coreSimulationSettings - Simulation settings that will be used for simulating traces from a petrinet.
