文摘In this paper, we provide a counter example for a successful method, i.e. IMP-BOT method [6], based on ODE for unconstrained optimization. And we obtainthat methods based on BDF and the general trapezoidal metod for unconstrainedoptimization is bad efficient because these methods even if have A stability, not Lstability.
