中文说明： The default problem in this directory (main directory) is the Chebyshev problem. If any of the other problems shall be treated, go to the appropriate subdirectory and copy the files objfun.m, PlotIt.m, and Rundeopt.m to the main directory. The script file Rundeopt.m (Run DE optimization) is the main control file in the MATLAB ?environment. Plotting can be turned off by setting the variable I_plotting=0 in rundeopt.m. Per default this variable is set to 1. Various ways of plotting have been used for the different examples. Only the two-dimensional problems allow an animated view how the population evolves on the objective function surface. Other problems may simply use a progress plot for the objective function value. It is best to try the different examples to see how plotting has been used to monitor the optimization.
