WebFor the "Smart-Greedy" algorithm, we can prove that the sum of the values obtained by the two sub-algorithms is at least the optimal value for the fractional knapsack problem by noting that the "Relatively-Greedy" and "Dumb-Greedy" algorithms both take the entire next item (if it fits), and thus any feasible solution obtained by these algorithms … WebAs an example for an approximation algorithm, consider a greedy algorithm for solving subset-sum problem that starts with an empty solution subset and examines the input numbers in decreasing order of their values [16]. Each considered number is inserted into the current solution if and only if it is
