Introduction
This page presents how ITS-Tools do cope efficiently with the ReachabilityDeadlock 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 2036 runs (1018 for ITS-Tools and 1018 for GreatSPN, so there are 1018 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 | 403 | 0 | 562 | Smallest Memory Footprint | ||
| ITS-Tools = GreatSPN | — | — | 0 | Times tool wins | 747 | 218 |

| ITS-Tools < GreatSPN | — | — | 0 | Times tool wins | 683 | 282 |

| Error detected | 0 | 0 | 0 | |||
| Cannot Compute + Time-out | 0 | 403 | 53 | |||
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 2036 runs (1018 for ITS-Tools and 1018 for ITS-LoLa, so there are 1018 plots on each of the two charts).
