GreatSPN compared to other tools («Known» models, QuasiLiveness)
Last Updated
Jun 22, 2022

Introduction

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

GreatSPN versus ITS-Tools

Some statistics are displayed below, based on 2822 runs (1411 for GreatSPN and 1411 for ITS-Tools, so there are 1411 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing GreatSPN to ITS-Tools are shown (you may click on one graph to enlarge it).

Statistics on the executions
  GreatSPN ITS-Tools Both tools   GreatSPN ITS-Tools
All computed OK 1 526 780   Smallest Memory Footprint
GreatSPN = ITS-Tools 0 Times tool wins 453 854
GreatSPN > ITS-Tools 0   Shortest Execution Time
GreatSPN < ITS-Tools 0 Times tool wins 401 906
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 526 1 104


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

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

GreatSPN versus Tapaal

Some statistics are displayed below, based on 2822 runs (1411 for GreatSPN and 1411 for Tapaal, so there are 1411 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing GreatSPN to Tapaal are shown (you may click on one graph to enlarge it).

Statistics on the executions
  GreatSPN Tapaal Both tools   GreatSPN Tapaal
All computed OK 90 404 691   Smallest Memory Footprint
GreatSPN = Tapaal 0 Times tool wins 196 989
GreatSPN > Tapaal 0   Shortest Execution Time
GreatSPN < Tapaal 0 Times tool wins 304 881
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 404 90 226


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

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

GreatSPN versus 2021-gold

Some statistics are displayed below, based on 2822 runs (1411 for GreatSPN and 1411 for 2021-gold, so there are 1411 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing GreatSPN to 2021-gold are shown (you may click on one graph to enlarge it).

Statistics on the executions
  GreatSPN 2021-gold Both tools   GreatSPN 2021-gold
All computed OK 18 529 763   Smallest Memory Footprint
GreatSPN = 2021-gold 0 Times tool wins 467 843
GreatSPN > 2021-gold 0   Shortest Execution Time
GreatSPN < 2021-gold 0 Times tool wins 443 867
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 529 18 101


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 GreatSPN computed more values than 2021-gold, denote cases where GreatSPN computed less values than 2021-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.

GreatSPN wins when points are below the diagonal, 2021-gold wins when points are above the diagonal.
