题解UVA11387 The 3-Regular Graph(推理 + 建图) 题意 给nn个点,要求构造一张简单无向图,其中每个点入度都为33,若可以构造则输出边数与边(顺序随意),无法构造则输出ImpossibleImpossible 算法 推理qwqqwq 思路 首先,整张图的度数和应为n×3n×3,而每连一条边度数和增加22,故nn为奇数肯定不合法。另外,...
UVA11387 – The 3-Regular Graph(推理) 大家好,又见面了,我是全栈君。 题目链接 题意:给n个点,问能否画出一个无向图。且每一个顶点连接3条边。假设能够的话输出连接的边。 思路:当添加一条边时,总的无向图的度数会添加2,所以度数之和n*2为偶数。当n为奇数时,度数之和为奇数,所以不存在。当n为偶...

3-regular graphs are 2-reconstructibleA graph is -reconstructible if it is determined by its multiset of induced subgraphs obtained by deleting vertices. We prove that 3-regular graphs are 2-reconstructible.doi:10.1016/j.ejc.2020.103216Alexandr V. KostochkaMina NahviDouglas B. West...

For a graph G, let [Math Processing Error]f2(G) denote the largest number of vertices in a 2-regular subgraph of G. We determine the minimum of [Math Processing Error]f2(G) over 3-regular n-vertex simple graphs G. To do this, we prove that every 3-regular multigraph with exactly ...
A path cover of a graph is a set of disjoint paths so that every vertex in the graph is contained in one of the paths. The path cover number p ( G ) of graph G is the cardinality of a path cover with the minimum number of paths. Reed in 1996 conjectured that a 2-connected 3...
Let G = ( V , E ) be a finite loopless graph and let ( A , +) be an abelian group with identity 0. Then an A-magic labeling of G is a function $${\phi}$$ from E into A {0} such that for some $${a \...关键词: Group-magic labeling Zero-sum group-magic labeling DOI...
