Abstract
To obtain good approximate solutions of a combinatorial optimization problem such as traveling salesman problem and to enable its processing apparatus in form of massively parallel exclusive devices, an information carrier corresponding to the distribution of a plurality of points given on an n-dimensional space (n is an integer not smaller than 2), and time development and time reversal of the information carrier are used to process the information. The information carrier may be the density of particles or optical intensity corresponding to the distribution of the given points, and a diffusion process of the particles or a defocusing process is used as changes with time. The traveling salesman problem is solved by using this method.
