Introduction

This page presents how smpt do cope efficiently with the ReachabilityFireability examination face to the other participating tools. In this page, we consider «All» models.

The next sections will show chart comparing performances in terms of both memory and execution time.The x-axis corresponds to the challenging tool where the y-axes represents smpt' performances. Thus, points below the diagonal of a chart denote comparisons favorables to the tool while others corresponds to situations where the challenging tool performs better.

You might also find plots out of the range that denote the case were at least one tool could not answer appropriately (error, time-out, could not compute or did not competed).

smpt versus ITS-Tools

Some statistics are displayed below, based on 3906 runs (1953 for smpt and 1953 for ITS-Tools, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing smpt to ITS-Tools are shown (you may click on one graph to enlarge it).

Statistics on the executions
  smpt ITS-Tools Both tools   smpt ITS-Tools
All computed OK 15 49 1285   Smallest Memory Footprint
smpt = ITS-Tools — — 62 Times tool wins 894 1056
smpt > ITS-Tools — — 107   Shortest Execution Time
smpt < ITS-Tools — — 432 Times tool wins 624 1326
Do not compete 0 0 0
Error detected 0 1 0  
Cannot Compute + Time-out 49 14 3


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where smpt computed more values than ITS-Tools, denote cases where smpt computed less values than ITS-Tools, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

smpt wins when points are below the diagonal, ITS-Tools wins when points are above the diagonal.

smpt versus Tapaal

Some statistics are displayed below, based on 3906 runs (1953 for smpt and 1953 for Tapaal, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing smpt to Tapaal are shown (you may click on one graph to enlarge it).

Statistics on the executions
  smpt Tapaal Both tools   smpt Tapaal
All computed OK 0 51 1161   Smallest Memory Footprint
smpt = Tapaal — — 49 Times tool wins 421 1531
smpt > Tapaal — — 245   Shortest Execution Time
smpt < Tapaal — — 446 Times tool wins 801 1151
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 51 0 1


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where smpt computed more values than Tapaal, denote cases where smpt computed less values than Tapaal, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

smpt wins when points are below the diagonal, Tapaal wins when points are above the diagonal.

smpt versus TY

Some statistics are displayed below, based on 3906 runs (1953 for smpt and 1953 for TY, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing smpt to TY are shown (you may click on one graph to enlarge it).

Statistics on the executions
  smpt TY Both tools   smpt TY
All computed OK 1230 8 281   Smallest Memory Footprint
smpt = TY — — 1 Times tool wins 1608 301
smpt > TY — — 348   Shortest Execution Time
smpt < TY — — 41 Times tool wins 1637 272
Do not compete 0 0 0
Error detected 0 13 0  
Cannot Compute + Time-out 8 1217 44


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where smpt computed more values than TY, denote cases where smpt computed less values than TY, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

smpt wins when points are below the diagonal, TY wins when points are above the diagonal.

smpt versus 2025-gold

Some statistics are displayed below, based on 3906 runs (1953 for smpt and 1953 for 2025-gold, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing smpt to 2025-gold are shown (you may click on one graph to enlarge it).

Statistics on the executions
  smpt 2025-gold Both tools   smpt 2025-gold
All computed OK 1 50 1160   Smallest Memory Footprint
smpt = 2025-gold — — 45 Times tool wins 400 1551
smpt > 2025-gold — — 244   Shortest Execution Time
smpt < 2025-gold — — 451 Times tool wins 796 1155

Cannot Compute + Time-out 50 1 2


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where smpt computed more values than 2025-gold, denote cases where smpt computed less values than 2025-gold, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

smpt wins when points are below the diagonal, 2025-gold wins when points are above the diagonal.

smpt versus BVT-2026

Some statistics are displayed below, based on 3906 runs (1953 for smpt and 1953 for BVT-2026, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing smpt to BVT-2026 are shown (you may click on one graph to enlarge it).

Important: here, smpt is compared to BVT-2026. It is a good way to check how smpt compete in terms of resource consomption with the best tools (even virtual). When smpt is best, the corresponding plots are on the diagonal of the scatter plots chart.

Statistics on the executions
  smpt BVT-2026 Both tools   smpt BVT-2026
All computed OK 0 51 1341   Smallest Memory Footprint
smpt = BVT-2026 — — 28 Times tool wins 0 1952
smpt > BVT-2026 — — 0   Shortest Execution Time
smpt < BVT-2026 — — 532 Times tool wins 0 1952
Do not compete 0 1 0
Error detected 0 0 0  
Cannot Compute + Time-out 52 0 0


For this tool, there are no real execution so comparisons are useless.
