On labeling in graph visualization q
When visualizing graphs, it is essential to communicate the meaning of each graph object via text or graphical labels. Automatic placement of labels in a graph is an NP-Hard problem, for which efficient heuristic solutions have been recently developed. In this paper, we describe a general framework for modeling, drawing, editing, and automatic placement of labels respecting user constraints. In...
متن کاملL(p, q) labeling of d-dimensional grids
In this paper, we address the problem of λ labelings, that was introduced in the context of frequency assignment for telecommunication networks. In this model, stations within a given radius r must use frequencies that differ at least by a value p, while stations that are within a larger radius r′ > r must use frequencies that differ by at least another value q. The aim is to minimize the span ...
متن کاملquasirecognition by prime graph of $u_3(q)$ where $2 < q =p^{alpha} < 100$
let $g $ be a finite group and let $gamma(g)$ be the prime graph of g. assume $2 < q = p^{alpha} < 100$. we determine finite groups g such that $gamma(g) = gamma(u_3(q))$ and prove that if $q neq 3, 5, 9, 17$, then $u_3(q)$ is quasirecognizable by prime graph, i.e. if $g$ is a finite group with the same prime graph as the finite simple group $u_3(q)$, then $g$ has a un...
متن کاملThe First and Second Zagreb Indices, First and Second Zagreb Polynomials of HAC5C6C7[p,q] and HAC5C7[p,q] Nanotubes
Topological indices are numerical parameters of a molecular graph G which characterize its topology. On the other hands, computing the connectivity indices of molecular graphs is an important branch in chemical graph theory. Therefore, we compute First Zagreb index Zg <span style="font-family: TimesNewRomanPS-Italic...
متن کاملQuasirecognition by the prime graph of L_3(q) where 3 < q < 100
Let $G$ be a finite group. We construct the prime graph of $ G $,which is denoted by $ Gamma(G) $ as follows: the vertex set of thisgraph is the prime divisors of $ |G| $ and two distinct vertices $ p$ and $ q $ are joined by an edge if and only if $ G $ contains anelement of order $ pq $.In this paper, we determine finite groups $ G $ with $ Gamma(G) =Gamma(L_3(q)) $, $2 leq q < 100 $ and prov...
