What is a Greedy Algorithm?</h2></div> <div><h3>Answer:</h3> <div class="answer"><div><div><div class="AnswerBody"><p>We call algorithms <em>greedy</em> when they utilise the greedy property. The greedy property is:</p><blockquote><p>At that exact moment in time, what is the optimal choice to make?</p></blockquote><p>Greedy algorithms are <em>greedy</em>. They do not look into the future to decide the global optimal solution. They are only concerned with the optimal solution <em>locally</em>. This means that <strong>the overall optimal solution may differ from the solution the greedy algorithm chooses.</strong></p><p>They never look backwards at what they've done to see if they could optimise globally. This is the main difference between Greedy Algorithms and Dynamic Programming.</p></div></div><div class="row my-2"><div><span><i>Source:</i> <span><a href="https://skerritt.blog/greedy-algorithms/" rel="noreferrer" target="_blank" title="What is a Greedy Algorithm?

What Are Greedy Algorithms Used For?</h2></div> <div><h3>Answer:</h3> <div class="answer"><div><div><div class="AnswerBody"><p>Greedy algorithms are quick. A lot faster than the two other alternatives (Divide & Conquer, and Dynamic Programming). They're used because they're fast. Sometimes, Greedy algorithms give the global optimal solution every time. Some of these algorithms are:</p><ul><li>Dijkstra's Algorithm</li><li>Kruskal's algorithm</li><li>Prim's algorithm</li><li>Huffman trees</li></ul><p>These algorithms are Greedy, and their Greedy solution gives the optimal solution.</p></div></div><div class="row my-2"><div><span><i>Source:</i> <span><a href="https://skerritt.blog/" rel="noreferrer" target="_blank" title="What Are Greedy Algorithms Used For?
