终于开始了研究生阶段的学习生活，繁琐的入学相关事宜也处理得差很少了。在9月5号，咱们实验室召开了第一次小组会议，导师也相继给咱们指定了各自的研究方向，不出意外，我接下来将围绕智能优化算法在太阳能电池方面的应用展开学习和研究。算法

从6号到9号，我用三天时间看完了两篇关于标准差分进化算法的英文文献，虽然在完成本科毕业设计的时候也简单接触了差分进化算法，可是并无本身动手实现，只是粗略地了解了算法流程，而此次则是仔细阅读了文献中的伪代码，参考了一些别人的代码。在这个过程当中，我发现不少网上的代码有的没有进行封装，或者有的会出现或多或少的bug，因此最后本身尝试用matlab对别人的代码按照本身对差分进化算法的理解作了必定的修改实现，若是你们发现有不正确的地方，欢迎留言指正。下面给出两篇英文文献名以及具体的matlab代码。session

Algorithms of global optimization and their applications (English)

Global Optimization, Evolutionary Algorithms and their Application to Computational Statistics

Stochastic algorithms of global optimization

In 1993 we started to deal with stochastic algorithms of global optimization. We modified the Controlled Random Search algorithm (Price 1976) by randomizing the reflection in simplex. The modified CRS algorithm was applied to estimating parameters of non-linear regression models and also in the shape optimization problem. For the testing of the stochastic algorithms a set of fourteen difficult non-linear regression tasks was collected. This collection can be downloaded here, the description of the tasks and references are in the file nlmod14.pdf (zip), data in text format are in the file models.zip.

Self-adaptive Algorithms for Global Optimization – MATLAB and C++ Library Including Parallel Implementation for Many Processors

Introduction

The Matlab program library has been established in the frame of the project201/05/0284 of the Czech Grant Agency at University of Ostrava in 2006.The extension by C++ version comes from next period and the parallel versionof C++ library is the result of the project supported by the European RegionalDevelopment Fund in the IT4Innovations Centre of Excellence project(CZ.1.05/1.1.00/02.0070)

Project team:

Josef Tvrdík, Department of Comp. Science, University of Ostrava,
Viktor Pavliska, Institute for Research and Applications of Fuzzy Modeling,University of Ostrava,
Radek Valášek, Institute for Research and Applications of Fuzzy Modeling,University of Ostrava,
Radka Poláková, Institute for Research and Applications of Fuzzy Modeling,University of Ostrava,
Hashim Habiballa, Department of Comp. Science, University of Ostrava,

The aim of this library is to make new self-adaptive stochastic algorithmsaccessible for potential users and facilitate the use of the self-adaptivealgorithms in practical problems. The self-adaptation of the algorithms meansthat the user need not set up their control parameters by preliminarytrial-and-error numerical experiment.

The library includes source codes of algorithms:
