Algorithms from Scratch
Solving Complex Problems with Simple Code · 2026
Algorithms from Scratch builds the core ideas of computing in plain, self-contained Python, with no libraries doing the thinking for you. Optimization, search, genetic algorithms, Monte Carlo simulation, Markov chains and graph problems are each worked through from first principles, in short programs you can read from top to bottom.
It is a book for people who want to understand what their code is doing. At a time when a great deal of code is generated by AI or borrowed from ready-made packages, Husain makes the case for knowing how the machinery works, and shows how far simple, carefully written code can go. Along the way he covers the tools he likes best in Python, from map and reduce to list comprehensions. It suits beginners and working programmers alike.
