[SCIP] Pleaseeee help me

[Jakob Witzig]

Hi Berna,

have you already installed SCIP? If not, a tutorial can be found here: 
http://scip.zib.de/doc/html/MAKE.php

Afterwards, you have to formulate your problem in a file format SCIP can 
read. A list of all readable file formats can be found here: 
http://scip.zib.de/doc/html/group__FILEREADERS.php

In your case it will be the easiest way to use the lp format. You can 
read the description given by CPLEX: 
http://scip.zib.de/doc/html/group__FILEREADERS.php. Since your problem 
is very small you can use write the lp file by hand. If want to solve 
larger problem you should use a modeling language, e.g., ZIMPL: 
http://zimpl.zib.de/

After you have your lp file (or another file that can read by SCIP) you 
should use the interactive shell: http://scip.zib.de/doc/html/SHELL.php

Please keep in mind, the mailing list and the community is not here to 
do your homework. Before you write a mail please use the search 
function: 
https://www.google.de/?gfe_rd=cr&ei=ZZhZVrXaJ8OK8Qf0o4awAw&gws_rd=ssl#q=site:listserv.zib.de%2Fpipermail%2Fscip 
maybe your problem was already discussed and solved.
If you would like to discuss an approach, found a bug or you would like 
to know whether your ideas can be realized with SCIP the community will 
try there best to help you.

Best
Jakob
