[Scip] Setting Branching Priority with .set file

[Jakob Witzig]

Hi lotu1,

my first answer was not complete in probably to general. First, set the 
priority of variables through a *.set file is not possible but you can 
change the priority by using the interactive shell after loading your 
problem.

A workaround would be using a "command file", e.g., myCommands.txt. 
Therefore, you use a file with some content like this:

read myFile
set branching priority myVar1 prio1
set branching priority myVar2 prio2
optimize
quit

and you execute SCIP with the command "scip < myCommands.txt"

Best,
Jakob
