Projects

Adiar

github.com/ssoelvsten/adiar

Following up on the work of Lars Arge in 1996, Adiar provides an easy-to-use implementation of Binary Decision Diagrams that make use of Time-Forward Processing to achieve efficient manipulation of BDDs, that far outgrow the memory limit of the given machine.

Wordrow

wordrow.io

Wordrow is a reimplementation of the classic internet puzzle game Text Twist as a static React (PWA) webpage with a modern and sleek design. To make it static, all games are pre-computed from the entire dictionary with an implementation of the Anatree data structure in C++.
