Last Updated
May 14, 2023

Introduction

This page presents how LoLA do cope efficiently with the ReachabilityDeadlock examination face to the other participating tools. In this page, we consider «Surprise» 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 122 runs (61 for LoLA and 61 for GreatSPN, so there are 61 plots on each of the two charts). Each execution was allowed 30 minutes 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 6 9 28   Smallest Memory Footprint
LoLA = GreatSPN 0 Times tool wins 19 24
LoLA > GreatSPN 0   Shortest Execution Time
LoLA < GreatSPN 0 Times tool wins 29 14
Do not compete 0 0 0
Error detected 0 0 0  
Cannot Compute + Time-out 9 6 18


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.
