Calculate an MST with Ant Colony Optimization in Python

Ant Colony Optimization is an old but still often applied construction heuristic to develop solutions using nature inspired behavior. The heuristic mimics the behavior of ants when finding shortest paths to between their nests and some kind of attraction, i.e. a food-source. The main idea are the pheromone trails, which ants leave behind, when travelling… Read more Calculate an MST with Ant Colony Optimization in Python

Marquee on a 8×8 LED Matrix Display run by a Battery powered Arduino Pro Mini

In this post I’ll show you how to implement a marquee running on an Arduino Pro Mini (5V). The project uses a slightly adapted version of the C source we developed for running the same project based on a Raspberry Pi 3B+. The main changes werd applied due to the two function void setup() and… Read more Marquee on a 8×8 LED Matrix Display run by a Battery powered Arduino Pro Mini
