WebJan 1, 2024 · The seminal paper of Khuller, Moss and Naor [13] achieved the ratio of for budgeted maximum coverage, using a greedy algorithm. Their result inspired the later work of Sviridenko [19] that showed a simple greedy algorithm for maximizing a monotone submodular function subject to a knapsack constraint. For a single matroid constraint, … WebIt is also called greedy local search as it only looks to its good immediate neighbor state and not beyond that. The steps of a simple hill-climbing algorithm are listed below: Step 1: Evaluate the initial state. If it is the goal state, then return success and Stop. Step 2: Loop Until a solution is found or there is no new operator left to apply.
