A data scientist at a manufacturing firm is tasked with maximizing profit by determining the optimal production quantities for several products. The production of each product requires a specific amount of time on various machines, and each machine has a fixed number of available hours. The profit per unit of each product is constant. This scenario is a classic example of a problem that can be modeled with a linear objective function and a set of linear constraints. Which of the following is the most suitable method for finding the optimal solution in this constrained optimization problem?
The correct answer is the Simplex method. The scenario described is a classic linear programming (LP) problem, which involves optimizing a linear objective function (maximizing profit) subject to a set of linear constraints (limited machine hours). The Simplex method is a fundamental and widely used algorithm specifically designed to solve such linear programming problems by systematically examining the vertices of the feasible region to find the optimal solution.
The Traveling Salesman Problem is a constrained optimization problem, but it focuses on finding the shortest possible route that visits a set of locations exactly once, which is not applicable to this resource allocation scenario.
The multi-armed bandit algorithm is a form of unconstrained optimization used to solve the exploration-exploitation tradeoff, such as determining which version of a webpage to show users to maximize clicks. It is not designed for problems with explicit linear constraints like resource allocation.
Gradient descent is an iterative optimization algorithm for finding the minimum of a function. While used in many machine learning optimization tasks, it is not the standard or most efficient method for solving canonical linear programming problems, for which the Simplex method is guaranteed to find the exact optimal solution.
