Understanding Recurrence Relations Using Automata, Python Code, And Javascript Visualizations
Recurrence relations are very often taught in first or secondyear computer science and discrete mathematics courses. This post takes a somewhat different and more visual approach to understanding linear recurrences and solving them by drawing the link between linear recurrences, automata, and matrices, using the problem of generating all dominotilings of a board as the springboard. Code in Python and visualizations in JavaScript are used to demonstrate the ideas.

Understanding SAT by Implementing a Simple SAT Solver in Python
SAT is often described as the "mother of all NPcomplete problems." This post goes over what SAT is and why it is considered to be so important. A simple SAT solver is implemented using Python in the process.
