What is a feasible solution?

A feasible solution is one that satisfies the given problem constraints.

What is an optimal solution?

An optimal solution is a feasible solution that gives the minimum cost, and there can only be one optimal solution for any optimization problem.

How does the greedy method work?

The greedy method works by considering one feasible input at a time and including it in the solution.

Is the greedy method always the best option?

No, adopting a greedy approach may lead to a satisfactory result, but it may not necessarily be the best option available.

Key insights

💰

Greedy method is a strategy for solving optimization problems that require either minimum or maximum results.
🎯

An optimization problem is one that requires either a minimum or maximum result, and the optimal solution achieves the objective of the problem.
🚗

The Greedy Method approach to buying a car involves selecting the best brand and model based on desired features, rather than checking every available option.
💰

The greedy approach in selecting the "best" option may not necessarily lead to the actual best option.
💰

Giving every candidate a chance for multiple interviews would be time-consuming and costly, so filtering and selecting the best candidate is a more efficient approach.
