为寻找计算机自动绘制原始图形的方法,提出了通过遗传算法进行图形自动拼贴、分层次组合绘制的方法.首先对已有的图形进行层次划分、功能分解,分解成具有最小层次和最小单元的细胞图形;根据顾客需求以及输入的需求参数,建立多目标优化数学模型;然后采用改进的遗传算法,进行分层次搜索,搜索出若干个满足需求的细胞图形,最后进行图形拼贴,形成完整的计算机自动绘制图形.研究结果表明:采用这种方法能够由计算机自动选择出满足顾客需求的优化图形,并且能够由计算机自动拼贴出令人满意的完整图形.
In order to find a way to automatically draw the original graphics by computer, a method of automatic collage and hierarchical combination drawing by genetic algorithm is proposed.Firstly, the existing graphics are divided into layers and decomposed into the smallest layer and the smallest unit Cell graphics; according to customer needs and input demand parameters, the establishment of multi-objective optimization mathematical model; and then use the improved genetic algorithm, hierarchical search, search out a number of cell graphics to meet the needs, and finally collage graphics to form a complete Computer automatically draw graphics.The results show that: This method can be automatically selected by the computer to meet the needs of the customer optimization graphics, and can automatically collage the computer to a satisfactory complete graphics.
