      Performs a Monte Carlo simulation of an accepting Petri net without duplicate transitions and where the preset is always

      Parameters
      -------------
      log
          Event log
      net
          Accepting Petri net without duplicate transitions and where the preset is always distinct from the postset
      im
          Initial marking
      fm
          Final marking
      variant
          Variant of the algorithm to use:
          - Variants.PETRI_SEMAPH_FIFO
      parameters
          Parameters of the algorithm:
              Parameters.PARAM_NUM_SIMULATIONS => (default: 100)
              Parameters.PARAM_FORCE_DISTRIBUTION => Force a particular stochastic distribution (e.g. normal) when the stochastic map
              is discovered from the log (default: None; no distribution is forced)
              Parameters.PARAM_ENABLE_DIAGNOSTICS => Enable the printing of diagnostics (default: True)
              Parameters.PARAM_DIAGN_INTERVAL => Interval of time in which diagnostics of the simulation are printed (default: 32)
              Parameters.PARAM_CASE_ARRIVAL_RATIO => Case arrival of new cases (default: None; inferred from the log)
              Parameters.PARAM_PROVIDED_SMAP => Stochastic map that is used in the simulation (default: None; inferred from the log)
              Parameters.PARAM_MAP_RESOURCES_PER_PLACE => Specification of the number of resources available per place
              (default: None; each place gets the default number of resources)
              Parameters.PARAM_DEFAULT_NUM_RESOURCES_PER_PLACE => Default number of resources per place when not specified
              (default: 1; each place gets 1 resource and has to wait for the resource to finish)
              Parameters.PARAM_SMALL_SCALE_FACTOR => Scale factor for the sleeping time of the actual simulation
              (default: 864000.0, 10gg)
              Parameters.PARAM_MAX_THREAD_EXECUTION_TIME => Maximum execution time per thread (default: 60.0, 1 minute)
  
      Returns
      ------------
      simulated_log
          Simulated event log
      simulation_result
          Result of the simulation:
              Outputs.OUTPUT_PLACES_INTERVAL_TREES => inteval trees that associate to each place the times in which it was occupied.
              Outputs.OUTPUT_TRANSITIONS_INTERVAL_TREES => interval trees that associate to each transition the intervals of time
              in which it could not fire because some token was in the output.
              Outputs.OUTPUT_CASES_EX_TIME => Throughput time of the cases included in the simulated log
              Outputs.OUTPUT_MEDIAN_CASES_EX_TIME => Median of the throughput times
              Outputs.OUTPUT_CASE_ARRIVAL_RATIO => Case arrival ratio that was specified in the simulation
              Outputs.OUTPUT_TOTAL_CASES_TIME => Total time occupied by cases of the simulated log
