VIII. 関数の極値(Extreme of Function)



The problem is again the same - looking for extreme of a function. But here you can define your own 3D function.


Graph represents search space and lines represent solutions (points in search space). The red line is the best solution, blue lines are the other ones.
You can enter your own function in a text field below graph (after change press enter or button Change). Below it you can define limits of function. Function can consist of x, y, pi, e, (, ), /, *, +, -, !, ^ and functions abs, acos, acosh, asin, asinh, atan, atanh, cos, cosh, ln, log, sin, sinh, sqr, sqrt, tan and tanh.
The graph can be rotated by dragging mouse over it.
You can also change crossover and mutation probability. Checkboxes control elitism and if it is looked for minimum or maximum.
Try to change the function and look, how GA works. If you find some interesting function, where GA behaves very good or very strange, you can email it to me.

Here is applet, but your browser does not support Java. If you want to see applets, please check browser requirements.
