K-Means Clustering is a popular algorithm in the field of unsupervised learning, which is used to divide data into groups or clusters. This approach makes it possible to identify patterns in data without requiring prior labels. For an introduction to the topic and a fun board game to illustrate the concepts of unsupervised learning, you can find information on this page. There you will find materials that help you better understand the basics of K-Means Clustering and apply them in practice.

Button Navigator - Dijkstra unplugged
The Dijkstra algorithm is an efficient method for determining the shortest path in a graph. It is widely used in networks, route planners, and many applications in computer science. Due to its ability to find optimal solutions, it plays a central role in graph theory and data analysis.

Q-Learning – Development with Scratch
In this article we outline the development of the QField with Scratch. We start by drawing the playing field and implementing the random movement of Scratch. In the next step, we introduce the Q table, which serves as the basis for reinforcing learning. Finally, we visualize Scratch's decisions through drawn arrows that represent his path on the playing field.

Q-Learning – unplugged
The QField serves to recreate the process of reinforcement learning with a piece of paper and a pen. This is about learning a way by using the unplugged algorithm. Unlike other algorithms that aim for optimal solutions, this approach focuses on learning through trial and feedback.

Reversi as an example of the Minimax algorithm (in Swift Playground)
Reversi, also known as Othello, is a strategic board game for two players played on an 8×8 board. The goal of the game is to have more stones of your color on the board than the opponent.

Abstract data types in school: Python implementations for download
In Lower Saxony, various abstract data types such as stack, queue, dynamic array and binary tree are treated in the school. The interfaces to this are explained in a handout (vgl. PDF-Datei).

What is a graph?
A graph is a mathematical structure consisting of vertices (nodes) and edges that connect these vertices. Graphs can be used to represent relationships between objects, for example in social networks or traffic networks. They are a central concept in graph theory and are used in many areas of computer science and mathematics.
