Both of these … WebThe edge weights determine the order in which the Dijkstra and Prim algorithms investigate (or attach) nodes. The sequence in which the nodes are examined (or connected) is constant if all of the edge weights are non-negative. This is because, even in the absence of a priority queue implementation, the algorithms will arbitrarily choose the ...

WebThe concept of MST allows weights of an arbitrary sign. The two most popular algorithms for finding MST (Kruskal's and Prim's) work fine with negative edges. Actually, you can just add a big positive constant to all the edges of your graph, making all the edges positive. … Webmultiple edges of the same weight crossing the cut, adding k does not e ect the possible options. (f)(T/F) Prim’s algorithm works even when there are negative edge weights in the graph. True. MST algorithms work ne with negative edge weights. This goes back to the cut property since for any cut, you can choose a negative edge weight as Web1. Suppose we have an undirected graph with weights that can be either positive or negative.
