Greedy Introduction Explanation

A greedy algorithm is a simple, intuitive algorithm that is used in optimization problems. The algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem. Greedy algorithms are quite successful in some problems, such as the Travelling Salesman Problem where At each step of the journey, visit the nearest unvisited city., or Dijkstra's algorithm, which is used to find the shortest path through a graph.
