Each round of presolving will be displayed in a single line, with a short summary at the end. Not much is happening for this instance, just the linear constraints get upgraded to more specific types. What do we see here? After "optimize", SCIP first goes into presolving. This opens the interactive shell, which should look somehow like this: Now start your binary, without any arguments. To follow this tutorial with a precompiled binary, we recommend downloading the instance stein27 from the MIPLIB 3.0 homepage. The SCIP source code distribution already comes with the example instance used throughout this tutorial. If you want to download a precompiled binary, go to the SCIP download section and download an appropriate binary for your operating system. The instance stein27, which will serve as an example in this tutorial, can be found under scipoptsuite-/scip-/check/instances/MIP/stein27.fzn.

If you want to download the source code of the SCIP standard distribution, we recommend to go to the SCIP download section, download the latest release (version 4.0.0 as of this writing), inflate the tarball (e.g., with "tar xzf scipoptsuite-.tgz"), and follow the instructions in the INSTALL file. SCIP can read files in LP, MPS, ZPL, WBO, FZN, PIP, OSiL, and other formats (see File Readers). Therefore, you can either download the SCIP standard distribution (which includes problem files) and compile it on your own or you can download a precompiled binary and an example problem separately. If you are using SCIP as a black box solver, here you will find some tips and tricks what you can do.įirst of all, we need a SCIP binary and an example problem file to work with.
