| Abstract(in English) | A quadratic assignment problem (QAP) is one of the NP-hard combinatorial optimization problems, which is very difficult to solve. Various heuristic methods to solve the QAP such as tabu search have been proposed. The tabu search technique has been implemented in a neural network form. Moreover chaotic dynamics has been used in the neural network to avoid the local minima problem. In order to achieve a high-speed massively parallel solution of the QAP, a dedicated analog integrated circuit system is necessary. The modified algorithm for the analog IC implementation has been proposed. In this paper, the algorithm is further modified taking a limited dynamic range of the analog circuitry into account. The effects of the modification are investigated through numerical simulations. Moreover, an overall system diagram for the QAP is proposed. The analog circuit components for the system are designed with MOSIS TSMC 0.35 μm CMOS process parameters. Characteristics of these circuits are confirmed with HSPICE simulations. |
