Last Updated
Jun 28, 2021 # Introduction

This page presents how Tapaal do cope efficiently with the ReachabilityCardinality 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 Tapaal' 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).

# Tapaal versus GreatSPN

Some statistics are displayed below, based on 2458 runs (1229 for Tapaal and 1229 for GreatSPN, so there are 1229 plots on each of the two charts). Each execution was allowed 1 hour and 16 GByte of memory. Then performance charts comparing Tapaal to GreatSPN are shown (you may click on one graph to enlarge it).

 Statistics on the executions Tapaal GreatSPN Both tools Tapaal GreatSPN All computed OK 516 0 392 Smallest Memory Footprint Tapaal = GreatSPN — — 1 Times tool wins 1153 69 Tapaal > GreatSPN — — 302 Shortest Execution Time Tapaal < GreatSPN — — 11 Times tool wins 1129 93 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 0 516 7

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

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

# Tapaal versus BVT-2021

Some statistics are displayed below, based on 2458 runs (1229 for Tapaal and 1229 for BVT-2021, so there are 1229 plots on each of the two charts).

Important: here, Tapaal is compared to BVT-2021. It is a good way to check how Tapaal compete in terms of resource consomption with the best tools (even virtual). When Tapaal is best, the corresponding plots are on the diagonal of the scatter plots chart.
