متن کاملYazilim Test Maliyet Fonksiyonlarinin Otomatik Olarak Kesfedilmesi
The testing of highly configurable systems almost always involves sampling enormous configuration spaces and testing representative instances of a system’s behavior. This sampling can be done by computing a combinatorial object, called a t-way covering array (CA). The covering arrays assume that the cost of configuring the system under test is the same for all configurations, however this is no...
متن کاملRoman Domination
In his article published in 1999, Ian Stewart discussed a strategy of Emperor Constantine for defending the Roman Empire. Motivated by this article, Cockayne et al.(2004) introduced the notion of Roman domination in graphs. Let G = (V,E) be a graph. A Roman dominating function of G is a function f : V → {0, 1, 2} such that every vertex v for which f(v) = 0 has a neighbor u with f(u) = 2. The we...

متن کاملThresholds for Roman domination
Define a Roman dominating function (RDF) of a graph G to be a function f : V (G) → {0, 1, 2} such that every u with f(u) = 0 has a neighbor v with f(v) = 2. The weight of f , w(f), is ∑ v∈V (G) f(v). The Roman domination number of G, γR(G), is the minimum weight of an RDF of G. It is easy to see that γ(G) ≤ γR(G) ≤ 2γ(G), where γ(G) is the domination number of G. In this paper, we determine pro...
