我做了一个小程序,但是运行总出现“??? Index exceeds matrix dimensions.”,去红色部分后,运行没有问题.我检查不出为什么,请各位高手指点以下.
for i=1:mant%%%每次均从同一点出发
[x]=find(max(YMV));%%为了保证每只蚂蚁仅仅找到一个最值
MAX_YMV=max(YMV);
for t=2:NC
city(i,t)=0;
city(i,t)=ceil(rand*mant);%%蚂蚁i在t刻所可能选择的位置
a=rand;%%%随即生成一个概率
for m=1:mant%%%下一城市城市的选择
if a<=PER(city(i,t-1),m)%%%%概率选择
city(i,t)=m;
else
continue;
end
end %%城市选择结束
if P(city(i,t))>=15523.9 && AV(city(i,t-1))-AV(city(i,t))>=0;%%当达到容许值且目标值减少时才移动
DELT(city(i,t-1),city(i,t))=DELT(city(i,t-1),city(i,t))+Q;%%设置初始值
T(city(i,t-1),city(i,t))= T(city(i,t-1),city(i,t))*rho+DELT(city(i,t-1),city(i,t));
%%蚂蚁i从位置city(i,t-1)到city(i,t)移动后路径上的信息量%%
%%AV(city(i,t-1))-AV(city(i,t))>0为了保证蚂蚁不走回头路及冤枉路%%
