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

Introduction

This page presents how ITS-Tools do cope efficiently with the UpperBounds 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 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 2822 runs (1411 for ITS-Tools and 1411 for GreatSPN, so there are 1411 plots on each of the two charts). Each execution was allowed 1 hour 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 592 0 796   Smallest Memory Footprint
ITS-Tools = GreatSPN 0 Times tool wins 899 503
ITS-Tools > GreatSPN 3   Shortest Execution Time
ITS-Tools < GreatSPN 11 Times tool wins 960 442
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 592 9


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 2822 runs (1411 for ITS-Tools and 1411 for Tapaal, so there are 1411 plots on each of the two charts). Each execution was allowed 1 hour 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 16 5 1027   Smallest Memory Footprint
ITS-Tools = Tapaal 53 Times tool wins 315 1092
ITS-Tools > Tapaal 282   Shortest Execution Time
ITS-Tools < Tapaal 24 Times tool wins 875 532
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 5 16 4


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 2822 runs (1411 for ITS-Tools and 1411 for 2021-gold, so there are 1411 plots on each of the two charts). Each execution was allowed 1 hour 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 17 0 1223   Smallest Memory Footprint
ITS-Tools = 2021-gold 107 Times tool wins 1183 219
ITS-Tools > 2021-gold 34   Shortest Execution Time
ITS-Tools < 2021-gold 21 Times tool wins 1068 334
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 17 9


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.
