WebAs what we said earlier, the greedy best-first search algorithm tries to explore the node that is closest to the goal. This algorithm evaluates nodes by using the heuristic function h(n), that is, the evaluation function is equal to the heuristic function, f(n) = h(n). This equivalency is what makes the search algorithm ‘greedy.’ Web1 day ago · Both experiments need two groups of images and two types of dictionaries. The first group of images are called training set images, and it has five images belonging to the CVG-UGR dataset (Cvg-ugr image database, 2024), see Fig. (5).This group was employed by the method of optimal directions (MOD)(Elad and Aharon, 2006) to build a dictionary …
