Abstract: We describe a new method for visualization of directed graphs. The method combines constraint programming techniques with a high performance force-directed placement (FDP) algorithm. The ...

Abstract: A popular method of force-directed graph drawing is multidimensional scaling using graph-theoretic distances as input. We present an algorithm to minimize its energy function, known as ...

Algebra can often feel intimidating, filled with strange symbols and abstract concepts that seem hard to grasp. But with the right strategies, anyone can unlock its logic and see how algebra connects ...

Python implementation of a primal active set method for sequential quadratic programming. A base ActiveSet class implements the generic form of the algorithm while derived classes implement the small ...

This file includes stroke(), which converts a path into a geometric object, like drawing with a pen. It even works on three-dimensional paths. You can make a dashed line or add arrow heads. The turtle ...
