Optimization of horizontal control networks by nonlinear programming
Abstract
Some practical aspects of horizontal control network design are considered, and the techniques of linear and nonlinear programming are briefly reviewed. Rotationally invariant constrains are written for the coordinate variance sum at each station. These constrains are also quasi-homogeneous in the sense that a Moore-Penrose generalized inverse is used in computation. The objective function to be minimized is a cost proportional to the number of observations. Results are displayed for serval test networks. Methods of improvement of the design algorithm are then discussed.
