Edge Span of L(p,q)-labeling on Graphs

Abstract

图的距离标号问题是经典图着色问题的一个自然推广,源于无线网络频率分配的优化问题. 在该问题的研究中,L(p,q)$标号是最早提出的,也是最具代表性的一种距离标号.$p,q$是两个非负整数,图$G$的一个$L(p,q)$标号定义为一个非负整数函数$c:V(G){0,1,2,}L(p,q)\$标号是最早提出的,也是最具代表性的一种距离标号.设\$p,q\$是两个非负整数, 图\$G\$的一个\$L(p,q)\$标号定义为一个非负整数函数 \$c:V(G)\mapsto\{0,1,2,\cdots\}, 满足:对\G$中的任意两个顶点$u$$vG\$中的任意两个顶点\$u\$和\$v,若\d(u,v)=1d(u,v)=1则\|c(u)-c(v)|\geqp; 若\d(u,v)=2d(u,v)=2则\c(u)c(v)|c(u)-c(v)|\geqq,其中\d(u,v)$表示顶点$u$$v$之间的距离....Thedistancelabelingofagraphisanaturalextensionoftheclassicalgraphcoloringproblem,whicharisesfromavariationofthechannelassignmentprobleminmultihopradiosystemsandwasfirstlyformulatedasagraphcoloringproblembyHale.Inthestudyofdistancelabelingproblem,thed(u,v)\$表示顶点\$u\$和\$v\$之间的距离....The distance labeling of a graph is a natural extension of the classical graph coloring problem, which arises from a variation of the channel assignment problem in multi-hop radio systems and was firstly formulated as a graph coloring problem by Hale.
