Greedy Best-First Search is a search algorithm that expands the most promising node chosen according to a specified heuristic function, aiming to find a solution quickly by prioritizing paths that appear to lead most directly to the goal. It can be efficient but is not guaranteed to find the optimal solution, as it only considers the heuristic cost and not the total cost from the start node.

Greedy Best-First Search

A search algorithm is a method used to retrieve information stored within some data structure, often optimizing for efficiency in terms of time and space. These algorithms are fundamental in computer science and vary widely in complexity, from simple linear searches to advanced techniques like binary searches and graph traversals.

A heuristic function is a problem-solving strategy that uses a practical method or various shortcuts to produce solutions that may not be optimal but are sufficient for reaching an immediate goal. It is often employed in algorithms to improve efficiency by estimating the cost of reaching a goal from a given state, especially in search algorithms like A*.

prioritizing paths

A goal is a desired outcome or target that an individual or organization aims to achieve, serving as a guiding principle for decision-making and behavior. Effective goals are specific, measurable, attainable, relevant, and time-bound, providing clarity and motivation for action.

Efficient search

An optimal solution is the best possible outcome that satisfies all constraints in a given problem, often found using optimization techniques. It is crucial in various fields such as mathematics, economics, and computer science, where it helps in decision-making and resource allocation to achieve maximum efficiency or minimum cost.

Total cost is the sum of all expenses a company incurs to produce a certain level of output, including both fixed and variable costs. It is crucial for businesses to understand and manage total costs to ensure profitability and make informed pricing and production decisions.
