ITS-Tools compared to other tools («Surprise» models, ReachabilityFireability)
Last Updated
Jun 28, 2020

Introduction

This page presents how ITS-Tools do cope efficiently with the ReachabilityFireability 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 422 runs (211 for ITS-Tools and 211 for GreatSPN, so there are 211 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 84 2 75   Smallest Memory Footprint
ITS-Tools = GreatSPN 0 Times tool wins 161 50
ITS-Tools > GreatSPN 50   Shortest Execution Time
ITS-Tools < GreatSPN 0 Times tool wins 177 34
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 2 84 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 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 ITS-LoLa

Some statistics are displayed below, based on 422 runs (211 for ITS-Tools and 211 for ITS-LoLa, so there are 211 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 ITS-LoLa are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools ITS-LoLa Both tools   ITS-Tools ITS-LoLa
All computed OK 0 0 194   Smallest Memory Footprint
ITS-Tools = ITS-LoLa 1 Times tool wins 106 103
ITS-Tools > ITS-LoLa 5   Shortest Execution Time
ITS-Tools < ITS-LoLa 9 Times tool wins 199 10
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 0 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 ITS-Tools computed more values than ITS-LoLa, denote cases where ITS-Tools computed less values than ITS-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.

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

ITS-Tools versus Tapaal

Some statistics are displayed below, based on 422 runs (211 for ITS-Tools and 211 for Tapaal, so there are 211 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 19 0 175   Smallest Memory Footprint
ITS-Tools = Tapaal 1 Times tool wins 163 46
ITS-Tools > Tapaal 7   Shortest Execution Time
ITS-Tools < Tapaal 7 Times tool wins 119 90
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 0 19 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 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 smart

Some statistics are displayed below, based on 422 runs (211 for ITS-Tools and 211 for smart, so there are 211 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 smart are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools smart Both tools   ITS-Tools smart

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 smart, denote cases where ITS-Tools computed less values than smart, 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, smart wins when points are above the diagonal.
