摘要

PROBLEM TO BE SOLVED: To provide a new dispersive route selection program that can relax the concentration of a mobile unit by dispersing route selection, and to provide a navigation program using the dispersive route selection program.;SOLUTION: A computer for dispersively selecting an optimum route is allowed to function as a route generating means for generating a plurality of routes, a required time calculating means for calculating a required time for each route, a candidate route selecting means for selecting up to the nth route as candidate routes in the order of required time, a random number generating means for generating a random number, and an optimum route selecting means for selecting an optimum route from the candidate routes by comparing the generated random number with a route selection table for determining the candidate route in which order is selected as an optimum route by using a selection probability distribution when the optimum route is stored in advance or a certain numeric value is given.;COPYRIGHT: (C)2005,JPO&NCIPI
