哈密顿图是一个 向图,由哈密顿爵士提出,由指定的起点前往指定的终点,途中经过所有其他节点且只经过一次。在图论中是指含有哈密顿回路的图,闭合的哈密顿路径称作哈密顿回路(Hamiltonian cycle),含有图中所有顶点的路径称作哈密顿路径(英语:Hamiltonian path,或Traceable path)。

哈密尔顿图的定义: G=(V,E)是一个图,若G中一条通路通过且仅通过每一个顶点一次,称这条通路为哈密尔顿通路。若G中一个圈通过且仅通过每一个顶点一次,称这个圈为哈密尔顿圈。若一个图存在哈密尔顿圈,就称为哈密尔顿图。

哈密尔顿图的必要条件: 若G=(V,E) 是一个哈密尔顿图,则对于V的每一个非空子集S,均有W(G-S) ≤|S|。其中|S|是S中的顶点数,W(G-S)表示图G擦去属于S中的顶点后,剩下子图的连通分枝的个数。

哈密尔顿图的充分条件: 设G=(V,E)是一个 向简单图,|V|=n. n≥3. 若对于任意的两个顶点u,v∊V,d(u)+d(v) ≥n,那么, G是哈密尔顿图 。

美国图论数学家奥勒在1960年给出了一个图是哈密尔顿图的充分条件:对于顶点个数大于2的图,如果图中任意不相邻的两点度的和大于或等于顶点总数,那这个图一定是哈密尔顿图。

寻找哈密顿路径是一个典型的NP-完全问题。后来人们也证明了,找一条哈密顿路的近似比为常数的近似算法也是NP-完全的。

寻找哈密顿路的确定算法虽然很难有多项式时间的,但是这并不意味着只能进行时间复杂度为{\displaystyle O(n\times n!)}{\displaystyle O(n\times n!)}暴力搜索。利用状态压缩动态规划,可以将时间复杂度降低到{\displaystyle O(2^{n}\cdot n^{3})}{\displaystyle O(2^{n}\cdot n^{3})},具体算法是建立方程f[S][j],表示经过了i个节点,节点都是集合S的,到达节点j时的最短路径。每次都按照点j所连的节点进行转移。

SB游戏,当初锁大陆IP时候的气量去哪里了?现在知道中国玩家才是爹但已经晚了。

Early Access Review
很鸡肋的动画制作,操作没有衔接感,跟steam上面其他用UE圈钱的游戏没啥两 ,差评。
