Codeforces Round 847 (Div. 3) G.Tokens on Graph (构造)

传送门 题目大意 ** 给定一个无向图,我们定义图中有四种点,一种是黑色的点表示终点,并且黑色的点始终是1号点,一种是红色的点,一种是灰色的点,最后一种就是没有颜色的点。** ** 游戏规则:我们必须移动任意一个灰色的点到相邻的点上,如果灰色的点移动到了红色的点上,那么我们可以移动其他灰色的点继续上 ......

图(Graph)与图论

听到图这个字,很多人会联想到图片、折线图、设计图等传统的图,今天要聊的图(Graph)是一种基本研究对象,用于表示实体与实体之间的关系。 先说结论: 图论:是组合数学分支,是主要研究图的学问,起源于柯尼斯堡七桥问题。 图(数学):是用于表示物体与物体之间存在某种关系的结构。数学抽象后的“物体”称作节 ......

为什么场景图叫图(Graph)而不是叫树(Tree)?

就如它的名字所说的一样,场景图是一个用于组织图形图像数据结构在计算机中显示的应用程序。一个通常的想法是场景往往被分为很多的部分,而出于某种通常的目的,这些部分最终都会被组合到一场,所以,场景图就是一个代表每个结点都可被分割与重组的图。再定义的严格一些,场景图就是一个非循环的图,所以它同时也体现出结点 ......
