一类随机区间捕捉有向图的控制数分布

The Distribution of the Domination Number of a Family of Random Interval Catch Digraphs

Elvan Ceyhan

摘要:

我们研究了一种新的接近图称为比例边接近捕捉有向图(PCD)在一个随机设置。PCD是近年来发展起来的一类特殊的随机捕获有向图,在统计模式分类和空间点模式分析中有着重要的应用。PCD也是一种特殊类型的交有向图;对于一维数据,比例边PCD族也是随机区间捕捉有向图族。我们提出了准确的(和渐近)分布的控制数的PCD家庭均匀(和非均匀)的数据在一维。我们还提供了几个扩展的随机捕获有向图放松的扩展和中心性参数,从而确定的参数的渐近分布是非退化的。我们观察到突然的跳跃(从简并到非简并或从一个非退化分布到另一个)的渐近分布的控制数在某些参数值。

英文摘要:

We study a new kind of proximity graphs called proportional-edge proximity catch digraphs (PCDs)in a randomized setting. PCDs are a special kind of random catch digraphs that have been developed recently and have applications in statistical pattern classification and spatial point pattern analysis. PCDs are also a special type of intersection digraphs; and for one-dimensional data, the proportional-edge PCD family is also a family of random interval catch digraphs. We present the exact (and asymptotic) distribution of the domination number of this PCD family for uniform (and non-uniform) data in one dimension. We also provide several extensions of this random catch digraph by relaxing the expansion and centrality parameters, thereby determine the parameters for which the asymptotic distribution is non-degenerate. We observe sudden jumps (from degeneracy to non-degeneracy or from a non-degenerate distribution to another) in the asymptotic distribution of the domination number at certain parameter values.
