模拟退火算法(Simulate Annealing Arithmetic,SAA)是一种通用概率演算法,用来在一个大的搜寻空间内找寻命题的最优解。它是基于Monte-Carlo迭代求解策略的一种随机寻优算法。 模拟退火算法是S.Kirkpatrick, C.D.Gelatt和M.P.Vecchi等人在1983年发明的,1985年,V.Černý也独立发明了此演
We give an online algorithm and show that its competitive ratio is at most k-1/m + 10 for m >= 2 and k + 2 for m = 1, where k is the number of blockages. This ratio is asymptotically tight since a lower bound Left perpendicular k/m Right perpendicular + 1 for this problem ...

In the PSO algorithm, the swarm is made up of a certain number of particles. Individual memory of a past experience retains the knowledge of where in the search space it performed best. At each iteration, all the particles move in the N-dimensional problem space according to the interaction...
The Traveling Salesman Problem Rules: Visit every city only once, then return back to the city you started in. Goal: Find the shortest possible route.Except for the Held-Karp algorithm (which is quite advanced and time consuming, (O(2nn2)O(2nn2)), and will not be described here), ...
