MIMRF-master
说明: 每个传感器具有一定的范围和精度,而且周围环境可能对它们产生干扰。即单传感器只能提供部分不精确的信息,从而不能排除对外界环境描述的歧义性。鉴于各传感器性能上的差异表现出的互补性,如果综合各个传感器的信息,就能得到比单一传感器所能提供的更准确可靠的信息。简言之,与单一传感器相比,多传感器数据融合由于信息的冗余性和互补性存在很多方面的优势。
多传感器融合(Each sensor has a certain range and accuracy, and the surrounding environment may interfere with them. That is to say, a single sensor can only provide some inaccurate information, so it can not rule out the ambiguity of the description of the external environment. In view of the complementarity of the differences in the performance of each sensor, if we synthesize the information of each sensor, we can get more accurate and reliable information than a single sensor can provide. In short, compared with a single sensor, multi-sensor data fusion has many advantages due to the redundancy and complementarity of information.)

Genetic-Algorithm
遗传算法(Genetic Algorithm)是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型,是一种通过模拟自然进化过程搜索最优解的方法,它最初由美国Michigan大学J.Holland教授于1975年首先提出来的,并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》,GA这个名称才逐渐为人所知,J.Holland教授所提出的GA通常为简单遗传算法(SGA)。(GA (Genetic Algorithm) is a simulation of Darwinian theory of evolution by natural selection and genetic mechanism of biological evolution of the computing model is a natural evolutionary process by simulating the optimal solution search method, which originally developed by the University of Michigan J.Holland Professor in 1975 first proposed and published an influential monograph " Adaptation in Natural and Artificial Systems" , GA This name was gradually known, J.Holland raised by Professor GA is usually simple genetic algorithm (SGA ).)
