2.1 算法思想的提出
2.1 algorithm propod ideas
所谓赋权汉密尔顿回路最小化问题是指，给定n个点及n个点两两之间的距离(或权数)，求一条回路，使之经过所有的点，且经过每个点仅一次，而整条回路(也称路径或边界)的总距离(或总权数)最小。
The so-called empowerment Hamilton loop minimization problem is to point to that, given n points and n points of the distance between (or opposite); a circuit weight, make through all the points, and after each point only once, and the whole loop (also called path or boundary) total distance (or total weighted function) minimum.
这一问题总是可以通过枚举法求出其解的，但由于枚举法的计算量过大，达到(n－1)!的数量级，因而，不是可行的方法。由此，人们提出了启发式算法来求解问题的近似解。所谓启发式算法，一般地讲，就是发现某些最优解所具备的特征或不应具备的特征，对应有特征而言，求出含应有特征的可行解；对不应有特征而言，从解空间中剔除不应有特征的解，再从

This problem can always through the enumeration method find out the solution, but due to the enumeration method of computing dimension, achieve (n - 1)! The magnitude of the issue, therefore, is not feasible method. Thus, people put forward to solve the problem of heuristic algorithm approximate solution. Alleged heuristic algorithm, generally speaking, is that some optimal solution has the characteristics or not should posss the characteristics of concerned, should ask the characteristics of the feasible solution containing should have characteristics; Should not have characteristics of concerned, from the solution space to remove the solution should not feature, and again from the remaining space looking for a solution. Therefore, heuristic algorithm can be defined as: from the optimal solution of the necessary conditions, and to design an effective algorithm, make out the solution meet the necessary condition.
就一般算法的本质而言，它是提供一种规范的过程，经由该过程得出的解满足问题最优解
高尔夫球的充分条件，即算法应该是问题最优解的充分条件的一种规范实现过程；而算法设计本身要求，算法必须给出解，因此，算法实际上还要满足最优解的必要条件，即算法可以定义为：算法是问题最优解的充分必要条件的一种规范实现过程。
dnf安全模式怎么解除>天蝎座的女生The esnce on the general algorithm, it is to provide a standard of process through this process, that the optimal solution meet problem, namely, the sufficient conditions for the existence of the optimal algorithm should be problems the sufficient conditions for the existence of a normal realization process; And algorithm design itlf requirements, algorithm, therefore, must be solution algorithm actually also to meet the necessary conditions of the optimal solution, namely algorithm can be defined as: algorithm is the optimal solution of the problem, the sufficient and necessary conditions of a normal realization process.
启发式算法只满足了算法的必要性条件，而没有满足其充分性条件，就一般意义而言，其结果不是问题的最优解。基于这一思路，经典启发式算法的做法就是从满足必要条件的解空间中找出一个解，这就产生了一个问题：这样的解是否还可以按某种规则改进?这就涉及
局部极值或重叠应用启发式算法的问题。如果存在局部极值或进一步优化的规则，那么，在已有解的基础上继续运用这些规则会极大改进算法的性能，这就是本算法的基本思路。
芳草的意思Heuristic algorithm only satisfy the necessary condition of the algorithm, and not meet its adequacy condition, general n, the result is not the problem of optimal solution. Bad on this idea, it is classic heuristic algorithm from meet the necessary conditions in the solution space find a solution, which has a problem: such a solution according to certain rules whether can also improve? This will involve local extremum or jackknife application of heuristic algorithm. If there are local extremum or further optimized rules, then, on the basis of the existing solution continued to u the rules will greatly improve performance of the algorithm, this is the basic thought of this algorithm.

依据上述局部优化的算法思想，对赋权汉密尔顿最小化问题进行分析。对该问题的一般形

式(包括平面和非平面)给出一条规则：最优路径上各点在插入路径时，其路径变化量最小。
Bad on the above local optimization algorithm for empowerment Hamilton thoughts, analyzes minimization problem. The general form of the problem and the plane (including plane are one rule:) the optimal path is inrted in different points on the route, the minimum amount of path changes.
这是本文给出优化算法的基础。关于该规则，用反证法可以简单地证明，即若最优路径上有某一点在插入路径时，其路径变化量不是最小，那么，至少还有一种插入法的路径变化量更少，则以路径变化量更小的插法来代替原插入方法，由此形成的回路其路径更短，而这与原路径最短的假设矛盾，所以，规则成立。
This is the basis of optimization algorithm are given in this paper. About the rules, with counter-evidence method can simply proof, the optimal path sacrificed if a certain point when inrted in, its path path is not the smallest amount of variation, then, there is at least a inrtion method path variation less, criterion with path variation inrted more sm

all method to replace the former inrt method, thus forming a loop its path, and this more short with the original path the shortest hypothesis is contradictory, so, rules established.
依据上面的分析，给出相应的算法。
Bad on the above analysis, and gives corresponding algorithm.

第0步，确定一个初始的循环起点。即以汉密尔顿回路上的某一点作为循环的起点，以该起点为当前点，转入第1步。
The first 0 step, sure an initial cycle starting point. Namely to Hamilton back at some point as a way of starting point and by the cycle for current points, to start the first step.
第1步，跨线切割形成孤立点。即在已形成的汉密尔顿回路上，以当前点为跨线的起点，
按路径方向作跨线，用跨线切割中间点，使该中间点成为孤立点，而该跨线成为一条边；此时，回路的路径上不包含全部点，故非然汉密尔顿回路，转入第2步。
Step 1, cross line form outlier. The Hamilton has formed namely in road, by current points to the starting point for cross line direction, by path across lines, u cross line middle point, make the intermediate point become isolated points, while the cross line become an edge; At this time, circuit path does not contain all points, so the ran Hamilton circuit, turn to step 2.
