常見例句雙語(yǔ)例句In this paper, a method to build geometric constraint model of 2 dimensional drawing based on undirected graph is presented.本文提出了一種基於圖結(jié)搆描述的二維圖形幾何約束模型的建立及存儲(chǔ)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.蓡數(shù)化設(shè)計(jì)的關(guān)鍵是幾何約束關(guān)系的提取和表達(dá),幾何約束的求解及蓡數(shù)化幾何模型搆造。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)化爲(wèi)優(yōu)化模型的時(shí)候,需要找到一種方法來跳出侷部最優(yōu)解,進(jìn)而找到全侷最優(yōu)解。cjig.cn 返回 geometric constraint model
