A tester which provides initial tests for MMCFBlock and any Solver
able to handle Linear Programs (such as MILPSolver and its derived
classes CPXMILPSolver, SCIPMILPSolver and GRBMILPSolver), as
well as for a few of the mechanics of the "core" SMS++ library.
This executable, given the filename and (optionally) filetype of one
Multicommodity Min-Cost Flow (MMCF) in one of the several supported file
formats, reads the instance in a MMCFBlock and solves it with a
:MILPSolver (or whatever appropriate solver the BlockSolverConfig
described by BSPar.txt dictates). It then loads the same problem with
the entirely different solver MMCFCplex and again solves it, comparing
the results (and printing the running time).
The usage of the executable is the following:
./MMCF_test file_name [typ]
typ = s*, c, p, o, d, u, m (lower or uppercase)
A batch file is provided that runs the test on a largish set of
MMCF instances (but not very large ones, so that the tests does end
in reasonable time). These instances are supposed to be in the data/
folder, but they need to be downloaded / generated before. The gen/
folder contains a genbatch which curls the instances from the
COMMALAB site and
generates another set with the included Mnetgen random generator
(also available at that page with instructions for generating even
larger ones if required). The download (but not the generation) is
also automatically done when installing the repo with CMake.
All the tests passing confirms that MMCFBlock correctly loads the
MMCF instances from file, and that no regressions have been done for
the tested modules, in particular for the used CDASolver.
