Introduction

This page presents how ITS-Tools do cope efficiently with the QuasiLiveness examination face to the other participating tools. In this page, we consider «All» 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 Tapaal

Some statistics are displayed below, based on 3906 runs (1953 for ITS-Tools and 1953 for Tapaal, so there are 1953 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 287 28 1460   Smallest Memory Footprint
ITS-Tools = Tapaal — — 0 Times tool wins 623 1152
ITS-Tools > Tapaal — — 0   Shortest Execution Time
ITS-Tools < Tapaal — — 0 Times tool wins 703 1072
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 28 287 178


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.

Error detected 0 0 0  
Cannot Compute + Time-out 29 937 177


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

ITS-Tools versus 2025-gold

Some statistics are displayed below, based on 3906 runs (1953 for ITS-Tools and 1953 for 2025-gold, so there are 1953 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 2025-gold are shown (you may click on one graph to enlarge it).

ITS-Tools versus BVT-2026

Some statistics are displayed below, based on 3906 runs (1953 for ITS-Tools and 1953 for BVT-2026, so there are 1953 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 BVT-2026 are shown (you may click on one graph to enlarge it).

Important: here, ITS-Tools is compared to BVT-2026. It is a good way to check how ITS-Tools compete in terms of resource consomption with the best tools (even virtual). When ITS-Tools is best, the corresponding plots are on the diagonal of the scatter plots chart.

Statistics on the executions
  ITS-Tools BVT-2026 Both tools   ITS-Tools BVT-2026
All computed OK 0 36 1747   Smallest Memory Footprint
ITS-Tools = BVT-2026 — — 0 Times tool wins 0 1783

For this tool, there are no real execution so comparisons are useless.
