[SCIP] Two questions about how to install examples of SCIP

[Stefan Vigerske]

Hi,

applications are currently not included in the binary packages for the 
SCIP Optimization Suite (there is an open issue to do this...). Here are 
executables for the applications that could work if you put them next to 
the libscip.dll (should be the directory where scip.exe gets installed): 
https://cloud.zib.de/s/HfGAHFxcJgfcRFe

Examples are meant to serve as a starting point for coding. Looking at 
their source code (following 
https://www.scipopt.org/doc-9.2.0/html/EXAMPLES.php or 
https://github.com/scipopt/scip/tree/v9-minor/examples) makes more sense 
than to actually run them, so there is no plan to include these into 
binary distributions.

To use CPLEX as LP solver, the SCIP/CPLEX interface needs to be included 
at build time. As CPLEX is proprietary software, and we probably cannot 
just redistribute CPLEX libraries without agreement from IBM, there are 
no prebuild SCIP installers available for SCIP with CPLEX. You will just 
have to build SCIP with CPLEX as LP solver from source.

Best,
Stefan

However, when I use SCIP Optimization Suite to install SCIP, I don't understand how to install and run applications/examples of SCIP, and how should I create a soft-link between SCIP and CPLEX and set CPLEX as the default linear programming solver in SCIP. I try to check the README.md file of the SCIP Optimization Suite on SCIP Doxygen Documentation: INSTALL (scipopt.org). However, I can't find the README.md via this link. So, I am wondering if you could assist me with questions I have regarding. Your expertise would be greatly appreciated.
