ITS-Tools compared to other tools («Known» models, LTLCardinality)
Last Updated

Introduction

This page presents how ITS-Tools do cope efficiently with the LTLCardinality 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 ITS-Tools.M

Some statistics are displayed below, based on 1938 runs (969 for ITS-Tools and 969 for ITS-Tools.M, so there are 969 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-Tools.M are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools ITS-Tools.M Both tools   ITS-Tools ITS-Tools.M
All computed OK 110 21 408   Smallest Memory Footprint
ITS-Tools = ITS-Tools.M 195 Times tool wins 413 412
ITS-Tools > ITS-Tools.M 34   Shortest Execution Time
ITS-Tools < ITS-Tools.M 57 Times tool wins 457 368
Do not compete 0 0 0
Error detected 0 0 1  
Cannot Compute + Time-out 21 110 138


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

ITS-Tools versus LoLA

Some statistics are displayed below, based on 1938 runs (969 for ITS-Tools and 969 for LoLA, so there are 969 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 LoLA are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools LoLA Both tools   ITS-Tools LoLA
All computed OK 3 133 355   Smallest Memory Footprint
ITS-Tools = LoLA 62 Times tool wins 515 422
ITS-Tools > LoLA 122   Shortest Execution Time
ITS-Tools < LoLA 262 Times tool wins 296 641
Do not compete 0 0 0
Error detected 1 1 0  
Cannot Compute + Time-out 132 2 32


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 LoLA, denote cases where ITS-Tools 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.

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

ITS-Tools versus enPAC

Some statistics are displayed below, based on 1938 runs (969 for ITS-Tools and 969 for enPAC, so there are 969 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 enPAC are shown (you may click on one graph to enlarge it).

Statistics on the executions
  ITS-Tools enPAC Both tools   ITS-Tools enPAC
All computed OK 777 1 24   Smallest Memory Footprint
ITS-Tools = enPAC 0 Times tool wins 793 12
ITS-Tools > enPAC 3   Shortest Execution Time
ITS-Tools < enPAC 0 Times tool wins 792 13
Do not compete 0 180 0
Error detected 1 61 0  
Cannot Compute + Time-out 58 594 106


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