checkSolution()

void checkSolution

(

SoPlexBase< R > &

soplex

)

performs external feasibility check according to check mode

Definition at line 261 of file soplexmain.cpp.

checkSolutionRational()

static void checkSolutionRational ( SoPlexBase< R > &  soplex )

static

performs external feasibility check with rational type

Todo:

implement external check; currently we use the internal methods for convenience
