WebGreedy Equivalence Search (GES) is nowadays the state of the art algorithm for learning Bayesian networks (BNs) from complete data. However, from a practical point of view, this algorithm may not be fast enough to work in high dimensionality domains. WebJan 24, 2024 · 1. 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.
