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

This page presents how LoLA do cope efficiently with the UpperBounds 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 449 4 638 Smallest Memory Footprint LoLA = GreatSPN — — 0 Times tool wins 1005 151 LoLA > GreatSPN — — 6 Shortest Execution Time LoLA < GreatSPN — — 59 Times tool wins 1049 107 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 4 449 73

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 ITS-Tools

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

 Statistics on the executions LoLA ITS-Tools Both tools LoLA ITS-Tools All computed OK 2 71 961 Smallest Memory Footprint LoLA = ITS-Tools — — 19 Times tool wins 897 326 LoLA > ITS-Tools — — 11 Shortest Execution Time LoLA < ITS-Tools — — 159 Times tool wins 901 322 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 71 2 6

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 ITS-Tools, denote cases where LoLA 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.

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

# LoLA versus Tapaal

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

 Statistics on the executions LoLA Tapaal Both tools LoLA Tapaal All computed OK 14 35 840 Smallest Memory Footprint LoLA = Tapaal — — 51 Times tool wins 802 385 LoLA > Tapaal — — 133 Shortest Execution Time LoLA < Tapaal — — 114 Times tool wins 910 277 Do not compete 0 0 0 Error detected 0 0 0 Cannot Compute + Time-out 35 14 42

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 Tapaal, denote cases where LoLA 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.

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

# LoLA versus 2020-gold

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for 2020-gold, 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 2020-gold are shown (you may click on one graph to enlarge it).

 Statistics on the executions LoLA 2020-gold Both tools LoLA 2020-gold All computed OK 511 9 600 Smallest Memory Footprint LoLA = 2020-gold — — 0 Times tool wins 1082 79 LoLA > 2020-gold — — 1 Shortest Execution Time LoLA < 2020-gold — — 40 Times tool wins 1083 78 Do not compete 0 0 0 Error detected 0 18 0 Cannot Compute + Time-out 9 493 68

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 2020-gold, denote cases where LoLA computed less values than 2020-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.

LoLA wins when points are below the diagonal, 2020-gold 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.

 Statistics on the executions LoLA BVT-2021 Both tools LoLA BVT-2021 All computed OK 0 72 968 Smallest Memory Footprint LoLA = BVT-2021 — — 11 Times tool wins 0 1224 LoLA > BVT-2021 — — 0 Shortest Execution Time LoLA < BVT-2021 — — 173 Times tool wins 0 1224 Do not compete 0 5 0 Error detected 0 0 0 Cannot Compute + Time-out 77 0 0

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 BVT-2021, denote cases where LoLA computed less values than BVT-2021, 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, BVT-2021 wins when points are above the diagonal.
