Cutting coal path planning of shearer up-drum based on double arc spline curve
Gong-kuang zidonghua, 2020 The life of the drum cutters is shortened and the coal output rate is reduced due to the problem that the shearer up-drum often cuts the roof rocks. It is therefore essential to plan the cutting path of the up-drum.

Attacking Shortest Paths by Cutting Edges
ACM Transactions on Knowledge Discovery from Data, 2023 Identifying shortest paths between nodes in a network is a common graph analysis problem that is important for many applications involving routing of resources. An adversary that can manipulate the graph structure could alter traffic patterns to gain some benefit (e.g., make more money by directing traffic to a toll road).

Sequence Hypergraphs: Paths, Flows, and Cuts [PDF]
, 2018 We introduce sequence hypergraphs by extending the concept of a directed edge (from simple directed graphs) to hypergraphs. Specifically, every hyperedge of a sequence hypergraph is defined as a sequence of vertices (not unlike a directed path). Sequence hypergraphs are motivated by problems in public transportation networks, as they conveniently ...
