CPX_KAPPA_STABLE
Concert Technology enum: KappaStable
#define CPX_KAPPA_STABLE 52
Numeric meaning (double):
To access the percentage of numerically stable simplex bases
(condition number less than 1e+7) among simplex bases
encountered during a MIP solve.
This feature is available only for simplex-based algorithms
when the parameter CPX_PARAM_MIPKAPPASTATS is set and after
CPLEX has processed at least one LP-basis during the solve.
Integer meaning: not applicable
