Last Updated
Jun 28, 2021 # Introduction

This page presents how Tapaal do cope efficiently with the Liveness examination face to the other participating tools. In this page, we consider «Surprise» 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 Tapaal' 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).

# Tapaal versus GreatSPN

Some statistics are displayed below, based on 364 runs (182 for Tapaal and 182 for GreatSPN, so there are 182 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing Tapaal to GreatSPN are shown (you may click on one graph to enlarge it).

 Statistics on the executions Tapaal GreatSPN Both tools Tapaal GreatSPN All computed OK 67 26 50 Smallest Memory Footprint Tapaal = GreatSPN — — 0 Times tool wins 107 36 Tapaal > GreatSPN — — 0 Shortest Execution Time Tapaal < GreatSPN — — 0 Times tool wins 103 40 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 26 67 39

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 Tapaal computed more values than GreatSPN, denote cases where Tapaal computed less values than GreatSPN, 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.

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

# Tapaal versus ITS-Tools

Some statistics are displayed below, based on 364 runs (182 for Tapaal and 182 for ITS-Tools, so there are 182 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing Tapaal to ITS-Tools are shown (you may click on one graph to enlarge it).

 Statistics on the executions Tapaal ITS-Tools Both tools Tapaal ITS-Tools All computed OK 0 46 117 Smallest Memory Footprint Tapaal = ITS-Tools — — 0 Times tool wins 83 80 Tapaal > ITS-Tools — — 0 Shortest Execution Time Tapaal < ITS-Tools — — 0 Times tool wins 60 103 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 46 0 19

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 Tapaal computed more values than ITS-Tools, denote cases where Tapaal 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.

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

# Tapaal versus LoLA

Some statistics are displayed below, based on 364 runs (182 for Tapaal and 182 for LoLA, so there are 182 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing Tapaal to LoLA are shown (you may click on one graph to enlarge it).

 Statistics on the executions Tapaal LoLA Both tools Tapaal LoLA All computed OK 0 44 117 Smallest Memory Footprint Tapaal = LoLA — — 0 Times tool wins 30 131 Tapaal > LoLA — — 0 Shortest Execution Time Tapaal < LoLA — — 0 Times tool wins 0 161 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 44 0 21

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 Tapaal computed more values than LoLA, denote cases where Tapaal computed less values than LoLA, 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.

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

# Tapaal versus 2020-gold

Some statistics are displayed below, based on 364 runs (182 for Tapaal and 182 for 2020-gold, so there are 182 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing Tapaal to 2020-gold are shown (you may click on one graph to enlarge it).

 Statistics on the executions Tapaal 2020-gold Both tools Tapaal 2020-gold All computed OK 4 4 113 Smallest Memory Footprint Tapaal = 2020-gold — — 0 Times tool wins 68 53 Tapaal > 2020-gold — — 0 Shortest Execution Time Tapaal < 2020-gold — — 0 Times tool wins 77 44 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 4 4 61

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 Tapaal computed more values than 2020-gold, denote cases where Tapaal computed less values than 2020-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.

Tapaal wins when points are below the diagonal, 2020-gold wins when points are above the diagonal.

# Tapaal versus BVT-2021

Some statistics are displayed below, based on 364 runs (182 for Tapaal and 182 for BVT-2021, so there are 182 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing Tapaal to BVT-2021 are shown (you may click on one graph to enlarge it).

Important: here, Tapaal is compared to BVT-2021. It is a good way to check how Tapaal compete in terms of resource consomption with the best tools (even virtual). When Tapaal is best, the corresponding plots are on the diagonal of the scatter plots chart.

 Statistics on the executions Tapaal BVT-2021 Both tools Tapaal BVT-2021 All computed OK 0 65 117 Smallest Memory Footprint Tapaal = BVT-2021 — — 0 Times tool wins 0 182 Tapaal > BVT-2021 — — 0 Shortest Execution Time Tapaal < BVT-2021 — — 0 Times tool wins 0 182 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 65 0 0

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 Tapaal computed more values than BVT-2021, denote cases where Tapaal computed less values than BVT-2021, 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.

Tapaal wins when points are below the diagonal, BVT-2021 wins when points are above the diagonal.
