pub unsafe extern "C" fn SCIPbendersSetSubproblemIsConvex(
benders: *mut SCIP_BENDERS,
probnumber: c_int,
isconvex: c_uint,
)Expand description
sets the flag indicating whether a subproblem is convex
It is possible that this can change during the solving process. One example is when the three-phase method is employed, where the first phase solves the convex relaxation of both the master and subproblems, the second phase reintroduces the integrality constraints to the master problem and the third phase then reintroduces integrality constraints to the subproblems.
