随机图的交叉数与应力

Crossing Numbers and Stress of Random Graphs

Markus Chimani, Hanna Döring, Matthias Reitzner

摘要:

考虑$\mathbb{R}^d$中随机点过程上的随机几何图。当且仅当两点的距离由指定的距离参数限定时,两点通过边连接。我们表明,投影到一个二维的平面上的图形预计会产生一个常数因子交叉数(和直线交叉数)近似。我们还表明,交叉数呈正相关的图形的投影的应力。

英文摘要:

Consider a random geometric graph over a random point process in $\mathbb{R}^d$. Two points are connected by an edge if and only if their distance is bounded by a prescribed distance parameter. We show that projecting the graph onto a two dimensional plane is expected to yield a constant-factor crossing number (and rectilinear crossing number) approximation. We also show that the crossing number is positively correlated to the stress of the graph's projection.
