Each of the sets of sufficient conditions is then shown to be equivalent to a corresponding unconstrained optimization problem. Hence, it can readily be solved by standard efficient optimization techniques. The usual trial-and-error method of finding the required parameters to satisfy the stability conditions can now be avoided.en© 1989 Taylor & Francis Ltd.Journal article003000766210.1080/00207728908910173A1989U6095000092-s2.0-002466371275993Lim, C.C.
