Practical Optimization Methods and Numerical Minimization

How do algorithms find the most efficient route, the lowest cost, or the best parameters for a machine learning model? At the heart of these solutions lies mathematical optimization, the science of finding the absolute best outcome from a set of choices. This text-based course guides you from the fundamental mathematical concepts of maxima and minima to implementing practical numerical solvers. You will learn how to translate real-world constraints into mathematical equations and solve them step-by-step using modern algorithmic approaches. What you'll learn: Understand foundational optimization terminology, including objective functions, decision variables, and constraints; Solve one-dimensional optimization problems using interval halving and golden section search methods; Apply multi-dimensional unconstrained techniques such as gradient descent and Newton's method; Configure constrained optimization problems using Lagrange multipliers and penalty function methods; Formulate linear programming problems and solve them using the Simplex algorithm; Implement modern optimization algorithms using Python libraries like SciPy to solve practical engineering and data problems. The course starts with basic mathematical definitions before guiding you through one-dimensional, multi-dimensional, and constrained optimization, concluding with practical linear programming applications. You will read detailed explanations, analyze step-by-step mathematical proofs, and study clean code implementations. Designed for beginners in data science, engineering, or mathematics, this course requires no advanced programming or calculus background to start.
