图形理论 meaning in English

graph theory
theory graph

The data structures are reminiscent of graphs , and the mathematical basis lies in graph theory
数据结构与图形关联，并以图形理论做为其数学基础。
This software , particularly intended for graph theoretical research , includes new algorithms based on our recent theoretical researches
这款软件特别关注图形理论的研究，包含了我们最近理论研究的新算法。
Because of the difference in environment , energy and process data , this paper uses analytic hierarchy process to build process planning evaluation model to add the relative efficiency of data . according to the result of relative index , an optimal green process planning approach is produced . the directed graph of process planning is built based on graph theory and the improved dijkstra algorithms is put forward to search the optimized process route
由于环境、能源及工艺数据标准的不一致，为了增加数据之间的相对有效性，本文引入层次分析法，建立了工艺决策层次评价模型，通过对相关指标的计算，得出了相对绿色的工艺决策方案：引用图形理论的基本原理，建立加工方案有向图网络，并提出改进的迪克斯特拉算法求解最优加工路线；最后给出绿色capp系统的原型框架和具体实现。
