14. Genetic calculation applets and other programs

By Knud Christensen - Lecture notes, front page (in Danish), Lecture notes, front page (in English)
A java interpreter should be enabled in your browser to run the applets ! !
By using the applets a general feature is that you can place your input in the green fields. The yellow fields can also be used for input, often in the next round of calculations.
Be careful not to leave any blanks (not visible) in these fields, so if the applet will not run, test if the cursor stands right next to the number in all green or yellow fields you have touched.
