Tools

Overall performance highly depends on problem formulation, solver, and tuning parameters. Our performance tools are designed to serve the different needs of our user community. Our goal is to help users determine reliable solvers for specific test models or if a new algorithm is to be tested, comparing it to other algorithms and competing approaches.

Our tools are meant as a starting point for investigating algorithm performance and are still being developed. In collaboration with the Performance World editorial board we seek to provide automation tools for collecting performance measurements and analyzing and visualizing test results.

For questions or comments, please contact the current Performance World Managing Editor.

ptools.zip

Includes the following tools:

pprocess.gms - performs all performance tools on a given set of trace files and combines output in a summary HTML page.
pprofile.gms - performance profile routine for solver comparisons for n solvers
plotprof.gms - performance profile plotting routine using Gnuplotxy (Windows only)
restime.gms - Resource time comparison utility for 2 solvers
schulz.gms - termination routine to ensure solvers terminate at resource time limit
square.gms - solver outcome comparison utility for 2 solvers
timings.gms - creates resource time table for n different solvers

Also includes the following sample data files, where solvers have been renamed to generic A, B, C to hide proprietary data:

A.trc - sample trace file for solver A
B.trc - sample trace file for solver B
C.trc - sample trace file for solver C

Also includes the following support utilities (not meant as stand-alone utilities):

readtrace.gms
