[SCIP] SCIP Optimization Suite 3.1.0

[ghasemzadeh at itu.edu.tr]

  Dear Hendel,

Thank you so much for your prompt and detailed response.

I prefer to implement the method in SCIP 6.0.1 but the available code  
can be run just in SCIP 3.1.0. I contacted the author and asked for a  
newer version of their implementation but they didn't have.

1) If you have the implementation of the code in SCIP6, it would be so  
helpful if I can have it. 

2) For the installation error I provided in my previous email, my  
system config is as follows:
OS: Ubuntu 18.04
Compiler: gcc 7.3.0
I used scipoptsuite-3.1.0

Indeed, The scipoptsuite suite is installed and tested completely and  
once I try to make the paper code implementation, it faces the  
problems which are screenshot in my previous email. 

3) BTW, as i understood it is better to use SCIP and CPLEX (as the LP  
solver) to implement that code instead of using scipoptsuit, right?

waiting for your response,

All the best,
Leila
