说明：  这是二战时期著名的，独领一时风骚的密码机Enigma的源代码，它真实的再现了Enigma的工作原理和真实原貌，希望有兴趣的朋友共同参详(This is the famous World War II, was the sole lead of 1:00 coquettish Enigma cipher machine source code, it is a true reproduction of the working principle of the Enigma and true original, want to have a friend interested in the common parameters are set)

The shuffled complex evolution with principal components analysis–University of California at Irvine (SP-UCI) method is a global optimization algorithm designed for high-dimensional and complex problems. It is based on the Shuffled Complex Evolution (SCE-UA) Method (by Dr. Qingyun Duan et al.), but solves a serious problem in searching over high-dimensional spaces," population degeneration". The population degeneration problem refers to the phenomenon that, when searching over the highdimensional parameter spaces, the population of the searching particles is very likely to collapse into a subspace of the parameter space, therefore losing the capability of exploring the entire parameter space. In addition, the SP-UCI method also combines the strength of shuffled complex, the Nelder-Mead simplex, and mutinormal resampling to achieve efficient and effective high-dimensional optimization.
