WebNov 11, 2024 · A selection sort could indeed be described as a greedy algorithm, in the sense that it: tries to choose an output (a permutation of its inputs) that optimizes a certain measure ("sortedness", which could be measured in various ways, e.g. by number of inversions), and; does so by breaking the task into smaller subproblems (for selection … WebStep 1: Define your solutions. Tell us what form your greedy solution takes, and what form some other solution takes (possibly the optimal solution). For exam-ple, let A be the solution constructed by the greedy algorithm, and let O be a (possibly optimal) solution. Step 2: Find a measure. Find a measure by which greedy stays ahead of the other ravi agarwal foreign policy
