摘　　要：控制网最优化设计中， 将点位优化时的选点范围近似为矩形。讨论了当测量控制网网形设计中控制点选点范围为不规则多边形时的点位最优化设计问题。以最优化的理论和方法为基础， 设计了一套在迭代过程中动态确定单维搜寻区间， 单维搜寻时采用０６１８ 法的控制点点位优化迭代算法。可获满意的计算效率， 并在算法上使点位优化处理的方法更具一般性。In the FOD of surveying control net, the selecting areas of control points usually are dealt with several rectangles. This paper discusses the surveying control point position optimization design problem, while the selecting areas of the points are not rectangle, but any irregular polygons. Based on optimization theory and methods, a kind of control point position optimization arithmetic program is designed: dynamic selecting search areas and “0 618 method' is used in single variate optimization searching. The caculating efficient is satisfied. This arithmetic program lets surveying control point position optimization problem becomes much more utility.
