There is something wrong in SA

Line 46 in c8eb453

dE = nextLen-FermatLen;%能量差

Line 46: if you calculate dE as dE = nextLen-FermatLen, the subsequent value P = exp(dE/k/T) will be larger than 1 in any case.
Therefore, your code cannot accept a new point with higher energy. So, the current code is exactly a random search...
