| Abstract(in English) | A tabu search was implemented on a chaotic neural network showing great performance in solving a quadratic assignment problem (QAP). We have implemented the exponential chaotic tabu search into a hardware system for size-10 QAPs. Experimental results with the hardware system confirmed superb performance of the system. In the original chaotic tabu search algorithm, each neuron is sequentially updated. Because of this sequential update, the hardware system cannot fully utilize its inherent parallelism. In this paper, we propose a synchronous updating scheme, which simultaneously updates all the neuronal states. Furthermore, we modify the chaotic neuron model for the synchronous updating scheme. In addition, we propose a new solution construction technique in which not only the neuron with the maximum internal state is used, but neurons with 2nd-, 3rd-, and so on, maximum internal states are also considered. Simulation results confirm quick and effective solving ability of the proposed synchronous exponential chaotic tabu search scheme. |
