WebAlso as stated earlier, the fraction knapsack can also be solved using greedy strategy i.e., by taking the items with the highest $\frac{value}{weight}$ ratio first. Thus, checking if the greedy algorithm … WebThe greedy algorithm results in a single edge matching of weight 1+ , while the optimum is the two edge matching of weight 2. Essentially a factor of 2 o . We claim that this example is worst possible Theorem 1. The weight of the matching Mreturned by the greedy algorithm is at least half of the weight of any matching M . Proof.
