The Simplex Algorithm is a cornerstone of linear programming, used to maximize or minimize linear functions under constraints. It iteratively explores feasible solutions through pivoting operations until the optimal solution is found or unboundedness is determined. Its practicality extends to various sectors, enabling efficient resource allocation and strategic planning. The Dual Simplex Method offers an alternative for specific scenarios, enhancing the algorithm's robustness and application in real-world problems.
