我的从属虚拟机出现故障,我猜这是因为 DFS 使用率为 100%。您能否给出一个系统的方法来解决这个问题?是防火墙问题吗?容量问题或可能导致该问题的原因以及如何解决?

第一:我承认它是编程竞赛的一部分(赢得胜利的东西或其他东西)
我在阅读了问题并尝试了以下算法后得出以下结论.
给定Undirected Connected Graph of nvertices,
count = 0
For i=1 to n:
remove(ith vertex)
check for connectivity of graph with remaining vertices
if connected
then increment count
attach the removed vertex back
print count

我已经通过两种方式实现了这个:(1)DFS(2)Disjoint-Set Union,但没有一种算法足以获得AC.是否有更好的方法可以做到这一点?我不需要详细的解释,几句话就会做,休息我会弄清楚或者死的尝试:p.谢谢!

我正在使用Windows Server 2012(默认情况下带有各种DFS CmdLets)。
我想做的是获取由域中其他DFS服务器(Win Srv 2008 R2)托管的特定UNC共享的ComputerName和local path。
一个例子:
Get-DfsnFolderTarget -Path '\\domain.net\share\folder\'

预期结果:
ComputerName = 'Server1'
Path = 'E\Home\folder'

我并不是真正的网络工程师,但似乎找不到基于UNC路径检索此信息的方法。每次我尝试上面的CmdLet时,都会出现错误:

问题是要通过水平,垂直或对角线移动来计算从(1,1)到(N,N)的到达次数。
如果用BFS解决问题(最坏的情况)需要1331.0毫秒,而用DFS解决则花费了62.0毫秒。(我已经创建并测试了16 * 16数组。)
