WebI'm reading about Dijkstra's algorithm in CLRS, Third Edition (p. 662). Here is a part from the book I don't understand: If the graph is sufficiently sparse — in particular, E = o (V^2/lg V) — we can improve the algorithm by implementing the min-priority queue with a binary min-heap. Why should the graph be sparse? Here is another part:
