We have developed an amoeba-inspired electronic computing system for solving traveling salesman problem (TSP), called “electronic amoeba”, and demonstrated that the electronic amoeba can find a solution of TSP. TSP is one of the optimization problems and an intractable problem for conventional computers. The state variables of the electronic amoeba, fully implemented by analog circuits, oscillate because of delay due to parasitic capacitances on the analog circuits. In this paper, we investigate the influence of the delay on the solution-searching performance of the electronic amoeba by numerical simulation.
