Entries in the “id” column represent the numeric identifiers placed at the right of each PBLSTL statement. The “% true PBLSTL” column describes what percentage of the 500 executions concluded that the PBLSTL statement is true. “#total STML” represents the total number of STML files evaluated for the PBLSTL statement; columns “#true STML” and “#false STML” represent the number of STML files for which the PBLSTL statement was evaluated true, respectively false.“ μ” and “ σ” represent the mean and standard deviation. “Exec. times” presents the average model checking execution time for each PBLSTL evaluation using the “minutes:seconds” format.
