We consider an inhomogeneous version of the Barak–Erdős graph, i.e. a directed Erdős–Rényi random graph on with no loop. Given a Riemann-integrable non-negative function on and , we define as the random graph with vertex set such that for each the directed edge is present with probability , independently of any other edge. We denote by the length of the shortest path between vertices 1 and , and take interest in the asymptotic behaviour of as .

关于稀疏 Barak-Erdős 图中最短路径的长度
我们考虑 Barak-Erdős 图的非齐次版本,即有向 Erdős-Rényi 随机图没有循环。给定一个黎曼可积非负函数和,我们定义作为具有顶点集的随机图这样对于每个有向边有可能存在,独立于任何其他边。我们表示顶点 1 和顶点之间的最短路径的长度,并对 的渐近行为感兴趣作为.
