Ollivier-Ricci curvature convergence in random geometric graphs

P van der Hoorn, WJ Cunningham, G Lippner… - Physical Review …, 2021 - APS
Connections between continuous and discrete worlds tend to be elusive. One example is
curvature. Even though there exist numerous nonequivalent definitions of graph curvature …

New perspective on sampling-based motion planning via random geometric graphs

K Solovey, O Salzman… - The International Journal …, 2018 - journals.sagepub.com
Roadmaps constructed by many sampling-based motion planners coincide, in the absence
of obstacles, with standard models of random geometric graphs (RGGs). Those models have …

Burning graphs: a probabilistic perspective

D Mitsche, P Prałat, E Roshanbin - Graphs and Combinatorics, 2017 - Springer
In this paper, we study a graph parameter that was recently introduced, the burning number,
focusing on a few probabilistic aspects of the problem. The original burning number is …

Geometric Machine Learning

M Weber - 2025 - Wiley Online Library
A cornerstone of machine learning is the identification and exploitation of structure in high‐

The longest path in the Price model

TS Evans, L Calmon, V Vasiliauskaite - Scientific reports, 2020 - nature.com
The Price model, the directed version of the Barabási–Albert model, produces a growing
directed acyclic graph. We look at variants of the model in which directed edges are added …
