Introduction to Greedy Techniques
Let’s go over the Greedy Techniques pattern, its real-world applications, and some problems we can solve with it.
We'll cover the following...
About the pattern
An algorithm is a series of steps used to solve a problem and reach a solution. In the world of problem-solving, there are various types of problem-solving algorithms designed for specific types of challenges. Among these, greedy algorithms are an approach for tackling optimization problems where we aim to find the best solution under given constraints.
Imagine being at a buffet, and we want to fill the plate with the most satisfying combination of dishes available, but there’s a catch: we can only make our choice one dish at a time, and once we move past a dish, we can’t go back to pick it up. In this scenario, a greedy approach would be to always choose the dish that looks most appealing to us at each step, hoping that we end up with the best possible meal.
Greedy is an algorithmic paradigm that builds up a solution piece by piece. It makes a series of choices, each time picking the option that seems best at the moment, the most greedy choice, with the goal of finding an overall optimal solution. They don’t worry about the future implications of these choices and focus only on maximizing immediate benefits. This ...
