More precisely, any change in the problem object that affects the basis matrix (adding rows, changing row/column of the constraint matrix, etc.) invalidates the basis factorization. > After invalidation of the basis factorization glp_warm_up has to be > called before calling glp_simplex. Not needed--glp_simplex does that automatically, if necessary. However, if the lp preprocessor is used, glp_simplex does not compute the basis factorization for the original lp at exit. _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org https://lists.gnu.org/mailman/listinfo/help-glpk
