Differential Evolution(JAVA)

package DeApp1;
/***********************************************************
** This is the main class of the DE development environ-  **
** ment. It's intention is to allow for the optimization  **
** of various objective functions with graphical output   **
** support.                                               **
**                                                        **
**                                                        **
** Version-Nr.:        1.0.3                              **
** Date:               2/24/99                            **
**                                                        **
**  Known Problems:                                       **
**  1) Coding and naming conventions not always adhered   **
**     to ->renaming makes program more difficult to read.**
**  6) Choice of strategy should not be just 1 automati-  **
**     cally.                                             **
** 10) For all problems objects are created, whether      **
**     they are needed or not.                            **
** 13) Inconsistent initialization. SetProblem() but not  **
**     SetStrategy(). This has to be cleaned up.          **
** 14) Remove access to status panel from control panel.  **
** 18) Number of plotting samples should be flexibly      **
**     adjustable depending on the problem.               **
