摘要

Recently we (Wang and Smith, 1998) proposed an alternative approach to chaotic simulated annealing as follows. Starting from the discretization of the analog Hopfield neural network (DAHNN) using Euler approximation, we use the discretizing time-step Δt as the annealing parameter, because the DAHNN is chaotic when the time-step At is chosen to be sufficiently large and stabilization is guaranteed when the time-step Δt is small enough. It is not necessary to carefully choose other system parameters to assure minimization of Hopfield energy function and network convergence. In this paper, we first review this approach and then demonstrate the approach by applying it to the traveling salesman problem. The dynamics of the neural network is also analyzed.
