WebApr 22, 2008 · We adopt a divide-and-conquer strategy, where the entire solution space of file assignments is divided into subspaces. Each subspace is an exclusive set of solutions sharing a common file replication instance. This allows us to utilize a greedy file allocation method for finding a good-quality heuristic solution within each subspace. By following the steps given below, you will be able to formulate a greedy solution for the given problem statement: 1. Step 1: In a given problem, find the best substructure or subproblem. 2. Step 2: Determine what the solution will include (e.g., largest sum, shortest path). 3. Step 3: Create an iterative … See more A Greedy algorithm is an approach to solving a problem that selects the most appropriate option based on the current situation.
