Mathematics

Being a mathematician, I created some mathematical applets and applications. These applets (with the exception of C.a.R.) may only be used on other pages with my permission.

• C.a.R. (Compass and Ruler)
  Large and powerful dynamical geometry program.
• Gauß Demonstration
  Little application to show the Gauß algorithm or the Simplex algorithm in class rooms step by step.
• Travelling Salesman Applet
  This applet demonstrates a local search for the shortest roundtrip through points in the plane, using neighborhood search from random global starting points.
• Growth of Water Lilies
  Monte Carlo Simulation of a statistical problem.
• Game of Life
  A study for software design from my Java class.
• The Catenary
  Simulation of a catenary with given length between two points.
• Mandelbrot's Apple Set
  A study about the speed of Java.
• Computing Interest Rates
  Solves the problem to compute the effective interest rate for an investment or a loan.
• Projection Demo
  3D projection of a cube to a plane.
• Interpolation Demo
  Another demo of interactive math.
• Analytic Mapping
  A Demo of an polynomial mapping the corners of a square to tour other points.
