1.The consistency of the Big M Method and Two-Phase Method in idea, auxiliary linear programming problem, initial feasible basis, initial simplex tableau and optimality criterion, etc. , is analyzed.
2.For a class of uncertain linear time-invariant systems whose characteristic polynomials are described by the so-called simplex polynomial family, their left-sector stability can be verified by avery simple criterion. This criterion is further simplified for low-order systems.
