The Greedy algorithm follows the path B -> C -> D -> H -> G which has the cost of 18, and the heuristic algorithm follows the path B -> E -> F -> H -> G which has the cost 25. This specific example shows that heuristic search is costlier. This example is not well crafted to show that solution of greedy search is not optimal.

WebMar 21, 2024 · A Graph is a non-linear data structure consisting of vertices and edges. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (E, V).
