Introduction

This page presents how TY do cope efficiently with the ReachabilityFireability 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 TY' 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).

TY versus ITS-Tools

Some statistics are displayed below, based on 3906 runs (1953 for TY and 1953 for ITS-Tools, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing TY to ITS-Tools are shown (you may click on one graph to enlarge it).

Statistics on the executions
  TY ITS-Tools Both tools   TY ITS-Tools
All computed OK 15 1271 322   Smallest Memory Footprint
TY = ITS-Tools — — 1 Times tool wins 215 1735
TY > ITS-Tools — — 1   Shortest Execution Time
TY < ITS-Tools — — 340 Times tool wins 190 1760
Do not compete 0 0 0
Error detected 13 1 0  
Cannot Compute + Time-out 1258 14 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 TY computed more values than ITS-Tools, denote cases where TY computed less values than ITS-Tools, 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.

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

TY versus smpt

Some statistics are displayed below, based on 3906 runs (1953 for TY and 1953 for smpt, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing TY to smpt are shown (you may click on one graph to enlarge it).

Statistics on the executions
  TY smpt Both tools   TY smpt
All computed OK 8 1230 281   Smallest Memory Footprint
TY = smpt — — 1 Times tool wins 301 1608
TY > smpt — — 41   Shortest Execution Time
TY < smpt — — 348 Times tool wins 272 1637
Do not compete 0 0 0
Error detected 13 0 0  
Cannot Compute + Time-out 1217 8 44


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 TY computed more values than smpt, denote cases where TY computed less values than smpt, 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.

TY wins when points are below the diagonal, smpt wins when points are above the diagonal.

TY versus Tapaal

Some statistics are displayed below, based on 3906 runs (1953 for TY and 1953 for Tapaal, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing TY to Tapaal are shown (you may click on one graph to enlarge it).

Statistics on the executions
  TY Tapaal Both tools   TY Tapaal
All computed OK 0 1273 323   Smallest Memory Footprint
TY = Tapaal — — 6 Times tool wins 208 1744
TY > Tapaal — — 0   Shortest Execution Time
TY < Tapaal — — 350 Times tool wins 236 1716
Do not compete 0 0 0
Error detected 13 0 0  
Cannot Compute + Time-out 1260 0 1


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 TY computed more values than Tapaal, denote cases where TY 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.

TY wins when points are below the diagonal, Tapaal wins when points are above the diagonal.

TY versus 2025-gold

Some statistics are displayed below, based on 3906 runs (1953 for TY and 1953 for 2025-gold, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing TY to 2025-gold are shown (you may click on one graph to enlarge it).

Statistics on the executions
  TY 2025-gold Both tools   TY 2025-gold
All computed OK 0 1271 323   Smallest Memory Footprint
TY = 2025-gold — — 6 Times tool wins 204 1746
TY > 2025-gold — — 0   Shortest Execution Time
TY < 2025-gold — — 350 Times tool wins 233 1717
Do not compete 0 0 0
Error detected 13 0 0  
Cannot Compute + Time-out 1258 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 TY computed more values than 2025-gold, denote cases where TY computed less values than 2025-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.

TY wins when points are below the diagonal, 2025-gold wins when points are above the diagonal.

TY versus BVT-2026

Some statistics are displayed below, based on 3906 runs (1953 for TY and 1953 for BVT-2026, so there are 1953 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing TY to BVT-2026 are shown (you may click on one graph to enlarge it).

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

Statistics on the executions
  TY BVT-2026 Both tools   TY BVT-2026
All computed OK 0 1273 323   Smallest Memory Footprint
TY = BVT-2026 — — 0 Times tool wins 0 1952
TY > BVT-2026 — — 0   Shortest Execution Time
TY < BVT-2026 — — 356 Times tool wins 0 1952
Do not compete 0 1 0
Error detected 13 0 0  
Cannot Compute + Time-out 1261 0 0


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