WebJun 8, 2024 · This is the most simple implementation of Depth First Search. As described in the applications it might be useful to also compute the entry and exit times and vertex color. We will color all vertices with the color 0, if we haven't visited them, with the color 1 if we visited them, and with the color 2, if we already exited the vertex. WebThe only element of depth-first search you tweak is the order in which children are investigated. The normal version proceeds in arbitrary order, i.e. in the order the children are stored. The only feasible alternative (towards shortest paths) I can come up with is a greedy approach, that is looking at children in order of their distance from ...
