Prim's algorithm using heap or unsorted array?
There's a question in my CS class asking that if the graph is a sparse graph, which is n^2 >> m, whether unsorted list with O(n^2) is more efficient than the binary heap O((m+n)logn). I'm a litt...

Minimum cost to make connect all nodes in one partition of a weighted undirected bipartite graph
Given a weighted undirected bipartite graph between partition A and B, I'm trying to find the minimum cost to connect all nodes in partition A.
It seems like I need to first find a Minimum Spanning Tr...

True or False: For an undirected graph, for every vertex, its edge with minimum weight is in a minimum spanning tree
I think this is true. With consideration to Prim's algorithm, the minimum edge of a vertex is either already in a tree, or will be selected eventually.
I also tried a lot of graph and they all seem co...

Time complexity of Prim's MST algorithm problem
I have a graph problem where we have:
There are exactly n vertices and n-1 edges.
All vertices are connected with each other – i.e. the network consists of
just one connected component. The network ...
