LoLA compared to other tools (��Known�� models, LTLFireability)
Last Updated
Jun 28, 2021 # Introduction

This page presents how LoLA do cope efficiently with the LTLFireability 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 LoLA' 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).

# LoLA versus GreatSPN

Some statistics are displayed below, based on 2458 runs (1229 for LoLA 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 LoLA to GreatSPN are shown (you may click on one graph to enlarge it).

 Statistics on the executions LoLA GreatSPN Both tools LoLA GreatSPN All computed OK 480 28 197 Smallest Memory Footprint LoLA = GreatSPN — — 25 Times tool wins 941 122 LoLA > GreatSPN — — 215 Shortest Execution Time LoLA < GreatSPN — — 118 Times tool wins 811 252 Do not compete 0 0 0 Error detected 5 91 1 Cannot Compute + Time-out 42 408 146

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

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

# LoLA versus BVT-2021

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for BVT-2021, 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 LoLA to BVT-2021 are shown (you may click on one graph to enlarge it).

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