常見例句雙語例句In this paper, a method to build geometric constraint model of 2 dimensional drawing based on undirected graph is presented.本文提出了一種基于圖結(jié)構(gòu)描述的二維圖形幾何約束模型的建立及存儲方法。The main problems of Parameter design are abstraction and expression of the geometric constraint relationship, solver of geometric constraint and creation of geometry model.參數(shù)化設計的關鍵是幾何約束關系的提取和表達,幾何約束的求解及參數(shù)化幾何模型構(gòu)造。When transferring a geometric constraint equation group into an optimization model, we need a method to jump out of the local beat solution so that we can find a best global solution.在將幾何約束問題的約束方程組轉(zhuǎn)化為優(yōu)化模型的時候,需要找到一種方法來跳出局部最優(yōu)解,進而找到全局最優(yōu)解。cjig.cn 返回 geometric constraint model
