这是一个SA求解tsp旅行商的matlab源代码

function plot(x0)
global dist;
global citynumber;
subplot(1,2,1);
plot( iters(1,:), iters(2,:) ), xlabel('迭代次数'), ylabel('最短路径路程'), title('路径优化过程');
subplot(1,2,2);
plot( citys(1,:), citys(2,:),'-b' ), xlabel('Ｘ坐标'), ylabel('Ｙ坐标'), title('求解路径');
hold on;

plot( citys(1,1), citys(2,1), 'r*', 'MarkerSize', 12 );
for i = 2:length(citys)
    if( mod( i, 2 ) == 1 )
        plot( citys(1,i), citys(2,i), 'r*', 'MarkerSize', 4 );
    else
        plot( citys(1,i), citys(2,i), 'bs', 'MarkerSize', 4 );
    end
