    ◆ rowintegral

    SCIP_Bool* MatrixStatistics::rowintegral

    Are all row entries of non-continuous columns and the row sides integral?

    ◆ rowequality

    SCIP_Bool* MatrixStatistics::rowequality

    Is the row an equality?

    ◆ rowbadnumerics

    SCIP_Bool* MatrixStatistics::rowbadnumerics

    Does the row contain large entries that make numerics difficult?
