探讨了矩形件和任意形状图案的排样优化问题的遗传算法求解,提出了剩余矩形表示法和条形图表示法。对于矩形排样，剩余矩形表示法提高了板材利用率，更容易得到较优解。对于任意形状图案排样，条形图表示法直接利用位图排样，不对图案作任何限制（允许有孔洞），排样速度很快。该算法已应用于智能印花分色系统中。-on rectangular pieces of arbitrary shape and pattern layout of genetic optimization algorithm. the remaining rectangle said law and bar charts representation. For rectangular nesting, said the remaining rectangular plate method to improve the efficiency and easier to obtain a better solution. For arbitrary shape pictorial layout, bar charts, said the use of Direct bitmap nesting, pictorial not make any restrictions (to allow holes), the layout very quickly. The algorithm was applied dichroic Intelligent Printing System.
