本文介绍了几种用于实域全局优化的进化算法。人们的兴趣集中在多模态问题上，这些问题通常会出现早熟收敛的困难。首先，简要回顾了标准遗传算法(SGA)的实数二进制编码及其在多峰问题中的不理想行为，并对其在克服早熟收敛方面的一些改进进行了综述。详细研究了两种基于微分算子的实数编码方法：由R.Storn和K.Price首次提出的非常现代有效的方法--微分进化(DE)和作者提出的简化实数编码微分遗传算法SADE。此外，还研究了SADE方法的一种改进，称为CERAF技术，使解的种群能够逃离局部极值。所有方法都在相同的目标函数集上进行了测试，并提出了一种基于可靠方法的系统比较。事实证明，实数编码方法在实域上表现出比二进制算法更好的性能，即使经过几次改进也是如此。此外，由于微分算子的自适应可能性，证明了它们的积极影响。从可靠性的角度看，用本文所述技术改进的实编码差分算法似乎是一种通用的、可靠的方法，能够解决所有提出的测试问题。

英文摘要：
This paper presents several types of evolutionary algorithms (EAs) used for global optimization on real domains. The interest has been focused on multimodal problems, where the difficulties of a premature convergence usually occurs. First the standard genetic algorithm (SGA) using binary encoding of real values and its unsatisfactory behavior with multimodal problems is briefly reviewed together with some improvements of fighting premature convergence. Two types of real encoded methods based on differential operators are examined in detail: the differential evolution (DE), a very modern and effective method firstly published by R. Storn and K. Price, and the simplified real-coded differential genetic algorithm SADE proposed by the authors. In addition, an improvement of the SADE method, called CERAF technology, enabling the population of solutions to escape from local extremes, is examined. All methods are tested on an identical set of objective functions and a systematic comparison based on a reliable methodology is presented. It is confirmed that real coded methods generally exhibit better behavior on real domains than the binary algorithms, even when extended by several improvements. Furthermore, the positive influence of the differential operators due to their possibility of self-adaptation is demonstrated. From the reliability point of view, it seems that the real encoded differential algorithm, improved by the technology described in this paper, is a universal and reliable method capable of solving all proposed test problems.
