Legacy KNN Visualizer

This project is a legacy Swing desktop app packaged as KnnPFEGb.jar. It is a local copy of the original University of Leicester KNN project, published as the "KNN and Potential Energy" applet at http://www.math.le.ac.uk/people/ag153/homepage/KNN/KNN3.html . If that original page is no longer reachable, a surviving public reference is the University of Leicester slide deck on SlideServe: https://www.slideserve.com/donna-cotton/knn-algorithm-and-cnn-data-reduction . Modern JDKs such as OpenJDK 26 no longer provide javax.swing.JApplet, so the repository includes a small compatibility shim and a launcher script.

Run

./run.sh

Requirements

• A JDK with java, javac, and jar available in PATH
• A reachable X11 desktop session (DISPLAY must point to a working GUI)

Notes

• The launcher builds the compatibility patch automatically into .build/.
• The original application jar is not rebuilt; it is started as-is.
