This repository is a collection of educational Python programs and Jupyter notebooks by Peter Norvig, focused on algorithmic problem-solving, puzzle-solving, and data analysis. It is not a deployable application or a formal research pipeline, but rather a set of self-contained explorations that demonstrate a wide range of programming techniques: constraint propagation, recursive search, dynamic programming, Monte Carlo simulation, n-gram language models, and symbolic computation. The code is well-structured, clearly documented, and often includes inline tests and performance benchmarks. While each notebook or script is independent, many contain reusable utility functions and algorithmic patterns that could be extracted for other projects. The repository includes data files (word lists, n-gram counts, bike ride logs, Sudoku puzzles) that are used as inputs for the explorations. The primary value is educational: it teaches how to think algorithmically and write clean, efficient Python code.
