ITS-Tools compared to other tools («Surprise» models, Liveness)
Last Updated
Jun 22, 2022

Introduction

This page presents how ITS-Tools 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 ITS-Tools' 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).

ITS-Tools versus GreatSPN

Some statistics are displayed below, based on 412 runs (206 for ITS-Tools and 206 for GreatSPN, so there are 206 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing ITS-Tools to GreatSPN are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools GreatSPN Both tools   ITS-Tools GreatSPN
All computed OK 126 0 77   Smallest Memory Footprint
ITS-Tools = GreatSPN 0 Times tool wins 174 29
ITS-Tools > GreatSPN 0   Shortest Execution Time
ITS-Tools < GreatSPN 0 Times tool wins 181 22
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 126 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 ITS-Tools computed more values than GreatSPN, denote cases where ITS-Tools 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.

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

ITS-Tools versus Tapaal

Some statistics are displayed below, based on 412 runs (206 for ITS-Tools and 206 for Tapaal, so there are 206 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing ITS-Tools to Tapaal are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools Tapaal Both tools   ITS-Tools Tapaal
All computed OK 19 0 184   Smallest Memory Footprint
ITS-Tools = Tapaal 0 Times tool wins 62 141
ITS-Tools > Tapaal 0   Shortest Execution Time
ITS-Tools < Tapaal 0 Times tool wins 115 88
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 19 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 ITS-Tools computed more values than Tapaal, denote cases where ITS-Tools 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.

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

ITS-Tools versus 2021-gold

Some statistics are displayed below, based on 412 runs (206 for ITS-Tools and 206 for 2021-gold, so there are 206 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing ITS-Tools to 2021-gold are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools 2021-gold Both tools   ITS-Tools 2021-gold
All computed OK 0 0 203   Smallest Memory Footprint
ITS-Tools = 2021-gold 0 Times tool wins 198 5
ITS-Tools > 2021-gold 0   Shortest Execution Time
ITS-Tools < 2021-gold 0 Times tool wins 198 5
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 0 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 ITS-Tools computed more values than 2021-gold, denote cases where ITS-Tools 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.

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