tourdist.m

用matlab实现模拟退火算法,是学习模拟退火算法的有用工具

function tour_distance = tourdist(tourvec, distance_matrix);


n_cities = length(tourvec);
city = 1;
tour_distance = 0;

while city <= (n_cities - 1),
   tour_distance = tour_distance + distance_matrix(tourvec(city), tourvec(city+1));
   city = city + 1;
end;

tour_distance = tour_distance + distance_matrix(tourvec(n_cities), tourvec(1));
