代码说明:

LZW压缩,实现文本的压缩,压缩比在2:1以上 ZW算法基于转换串表(字典)T,将输入字符串映射成定长(通常为12位)的码字。在12位4096种可能的代码中,256个代表单字符,剩下3840给出现的字符串。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • MOEA framework
    应用背景The MOEA Framework is a free and open source Java library for developing and experimenting with multiobjective evolutionary algorithms (MOEAs) and other general-purpose multiobjective optimization algorithms. The MOEA Framework supports genetic algorithms, differential evolution, particle swarm optimization, genetic programming, grammatical evolution, and more. A number of algorithms are provided out-of-the-box, including NSGA-II, NSGA-III, ε-MOEA, GDE3 and MOEA/D. In addition, the MOEA Framework provides the tools necessary to rapidly design, develop, execute and statistically test optimization algorithms.关键技术Its key features includes:   * Fast, reliable implementations of many state-of-the-art algorithms   * Extensible with custom algorithms, problems and operators   * Supports master-slave, island-model, and hybrid parallelization &n
