Hi,

Try if you get a SCIP shell if you do not include your own plugins.
If not, then something must have got lost when you modified the coloring
example.

c:\mybp\bin\coloring.mingw32_nt-6.0.x86.gnu.opt.spx -f NDR1.txt
where NDR1.txt need to be in the directory from which you execute this
command.
> Can you give some suggestions on the implementation?
Find out the differences between Coloring/main.c and your code, revert
them step by step, and see at which point things started to break.
