Description (last modified by )
Based upon Harald Schilly's SPKG for SCIP, here is a patch to enable the use of this solver through the usual interface for LP.
Requires #8172 (though none of GLPK, CBC or CPLEX needs to be installed)

Fixed ! The corresponding argument in sage is log=# in the solve method. 0 for no output, and integers to have progressdively more (only GLPk has different levels of output though, the others only understand 0/1 or none at all )

Hi Nathann,
two small things:
solve_scip
has no documentation/doctests- "the default solver is used (COIN if available, GLPK otherwise)" seems to be inaccurate since you also try SCIP whether it is available

Duplicate of #10879, so I'm marking this one as "needs_review" so it can be closed -- hoping this is the correct procedure.

wow, thank you!! just one thing, is it possible to enable verbose output if enabled? i don't know which parameter you have to set in Sage's MIP interface, but it is scip.solver(quiet=False) in scip.
