An opinionated interface to the SCIP solver in the C language. A restricted subset of the features is chosen, with the goal of making SCIP more accessible to novice users and other programming languages.
The following constraint types are supported: linear, quadratic, SOS1 and SOS2.
Furthermore, users can implement a lazy constraint by implementing a single callback function.
CSIP depends on the SCIP Optimization Suite.
Download and extract the source files, then build the shared library (containing SCIP and SoPlex) with
make SHARED=true GMP=false READLINE=false ZLIB=false scipoptlib
which will produce a file libscipopt.so.
To build CSIP, set the environment variable SCIPOPTDIR to point to the
directory that contains the scipoptsuite sources. CSIP needs the library in
${SCIPOPTDIR}/lib/scipoptlib.so and the C header files in
${SCIPOPTDIR}/scip-*/src/.
Run make to build CSIP, which will produce a shared library
libcsip.so.
To compile and execute the tests, run make test.
