记得上Algorithm的时候,教授举得例子就是说,DFS很像好奇的小孩,你给这个小孩几个盒子套盒子,好奇的小孩肯定会一个盒子打开后继续再在这个盒子里面搜索。 等把这一套盒子都打开完,再打开第二套的。 Wikipedia上的讲解是:“Depth-first search(DFS) is analgorithmfor traversing or searchingtreeorgraphdata structure...

Khan and Mehta [STACS19] presented several algorithms allowing trade-offs between space and passes, where O ( n k ) O(nk) space results in O ( n / k ) O(n/k) passes. They also empirically analyzed their algorithm to require only a few passes in practice for even O ( n ) O(n...
