Start by putting any one of the graph's vertices on top of a stack.The purpose of the algorithm is to mark each vertex as visited while avoiding cycles. Traversal means visiting all the nodes of a graph.Ī standard DFS implementation puts each vertex of the graph into one of two categories: Decrease Key and Delete Node Operations on a Fibonacci Heapĭepth first Search or Depth first traversal is a recursive algorithm for searching all the vertices of a graph or tree data structure.
