摘要
针对独立闭合环自动生成经典算法中多解性和环长未定两个问题,本文应用闭合环网形的信息矩阵,顾及边长因素,提出基于矩阵运算的新算法,生成的闭合环满足最短独立闭合环的所有要求。通过两种算法的GPS控制网闭合环搜索结果比较,验证了本文算法结果的唯一性和环长最短性。
To address the problems of multiple solutions and indefinite ring length in the classical independent closed loop algorithm,using the closed ring-shaped information matrix and taking into account the side element,this paper introduces a new algorithm based on matrix operations.The resulting closed loop meets all the requirements of the least independent closed loops.Through comparing the results of two algorithms in GPS network closed loop researching,the uniqueness of the result and the shortest length of ring are verified.
