mccs OCaml library
mccs (which stands for Multi Criteria CUDF Solver) is a CUDF problem solver developed at UNS during the European MANCOOSI project.
This repository contains a stripped-down version of the
mccs solver, taken from snapshot
1.1, with a binding as an OCaml library, and building with
GLPK source it links against is
also included within src/glpk, at version 4.63 (unmodified, apart from many
removed modules, corresponding to the parts that we don't use).
The binding enables interoperation with binary CUDF data from the OCaml CUDF library, and removes the native C++ parsers and printers from mccs.
Only the GLPK backend and the
lpsolve interface are compiled by default, but
that can be tuned by setting the MCCS_BACKENDS environment variable, at
compile-time, to a space-separated list of the following:
SYMPHONY. Note that, apart from
GLPK, you will need the corresponding
libraries installed, the backends will be dynamically linked, and these are

included GLPK version can be disabled by removing
