Dear SCIP mailing list users,
I'm a new user to SCIP as well as to this mailing list and - after
successfully solving some easier problems with SCIP to get familiar to
how the API works - came across a problem that seems to be a bit more of
a basic nature.
When running SCIPsolve after having created a problem and added
variables and constraints to it I get the following error(s) after the
presolving phase:
[src/scip/lpi_spx.cpp:3100] ERROR: SCIPlpiGetPrimalRay() not supported
by SoPlex
[src/scip/lp.c:13515] ERROR: Error <-6> in function call
[src/scip/lp.c:12257] ERROR: Error <-6> in function call
[src/scip/solve.c:830] ERROR: Error <-6> in function call
[src/scip/solve.c:1962] ERROR: Error <-6> in function call
[src/scip/solve.c:2680] ERROR: Error <-6> in function call
[src/scip/solve.c:3297] ERROR: Error <-6> in function call
[src/scip/scip.c:6829] ERROR: Error <-6> in function call
[ScipTest.cpp:531] ERROR: Error <-6> in function call
I really have no idea what might cause of this error. Any help with this
would be greatly appreciated!
Please let me know if you need any further information and especially
which informaton you need.
I should add that I'm a student of electrical engineering and not a
mathematician, so I'm not familiar with the theory behind SCIP or SoPlex.
Best regards,
Stephan
