When addressing optimization problems, one of the simplest and most beautiful solutions in computer science is the greedy algorithm. In this article, we will define what a greedy algorithm<\/strong> is, identify its properties, how it compares to dynamic programming<\/strong>, and finally, look at examples of life where greedy algorithms results in optimal solutions.<\/p>\n

What Is a Greedy Algorithm?<\/h2>\n

Greedy Algorithm<\/figcaption><\/figure>\n

A greedy algorithm<\/strong><\/a> is an algorithmic paradigm that makes the locally optimal choice at each stage with the intention of finding a global optimum. In other words, it will make each decision at an instant, based only on what seems best at that moment, and will not go back to individual previous choices.<\/p>\n

The common phrase that encapsulates these paradigm’s logic is: Select what looks best at this time and move ahead.<\/p>\n

History & Evolution of Greedy Algorithm<\/h2>\n

Greedy<\/span> has<\/span> been<\/span> a<\/span> part<\/span> of<\/span> the<\/span> study<\/span> of<\/span> algorithms<\/span> from<\/span> the<\/span> beginning<\/span>. It<\/span> wasn<\/span>‘<\/span>t<\/span> until<\/span> the 1950s that<\/span> researchers began to<\/span> formalize<\/span> greedy<\/span> approaches<\/span> as methods<\/span> for combinatorial optimization. Today, greedy solutions are<\/span> important<\/span> parts<\/span> of<\/span> AI heuristics, feature selection in<\/span> machine<\/span> learning<\/span>, and new<\/span> approaches<\/span> to<\/span> networking.<\/p>\n
