Webb3 jan. 2024 · Dual simplex is the default. I assume you mean by "revised simplex" the primal simplex method (CBC has no full-tableau simplex so in that sense all Simplex methods in CBC are "revised"). The interior point method can be selected with options=['barrier']. For large LPs it may make sense to try out these three methods. WebbPros of simplex: Given n decision variables, usually converges in O ( n) operations with O ( n) pivots. Takes advantage of geometry of problem: visits vertices of feasible set and checks each visited vertex for optimality. (In primal simplex, the reduced cost can be used for this check.)
