[Scip] optimal solution wrong?

[Stefan Vigerske]

Hi,

it works for me.
I tried SCIP 3.0.1 with CPLEX as LP solver on an OSiL translation of the 
instance and GAMS 24.0.2 on the original .gms file with SCIP 3.0 and 
either CPLEX and SOPLEX. Both on Linux 64bit.

If it does not work for you, please file a bugreport at
   https://www.edom.mi.uni-erlangen.de/cgi/scipweb/submit.pl
including information about which SCIP version you are using, on which 
platform, which external libraries you linked into SCIP, and how you 
feed the problem into SCIP.

Stefan

PS: 14.2031 is the value of of the initial solution, at least in case of 
osil and gms input.
