Continuous Numerical Optimization Fundamentals

Numerical optimization is at the core of modern machine learning, engineering design, and scientific computing. This written course provides a structured introduction to continuous optimization, breaking down mathematical concepts and algorithmic procedures into accessible, readable lessons. You will build an intuitive and practical understanding of how optimization algorithms find minimums and maximums across single-variable and multivariable functions. Starting with foundational definitions, calculus concepts, and convex analysis, you will progress toward implementing standard first-order and second-order methods. What you'll learn: - Understand core mathematical definitions including gradients, Hessians, convexity, and stationary points - Apply one-dimensional search methods such as bisection and golden-section search - Master unconstrained multivariable techniques including gradient descent, coordinate descent, and Newton-Raphson methods - Explore modern stochastic and adaptive optimization algorithms widely used in machine learning workflows - Analyze constrained optimization problems using Lagrange multipliers and penalty function methods - Practice formulating real-world mathematical optimization models and interpreting convergence behavior The course begins with foundational vocabulary and calculus essentials before walking through each algorithm step by step with clear text explanations and code snippets. Designed specifically for beginners, students, and engineers looking to understand the mechanics of optimization from the ground up, no advanced prior background in numerical analysis is required.
