The algorithms for the Eulerian cycle and Eulerian trail problems for a multiple graph
Моделирование и анализ информационных систем, 2023 In this paper, we study undirected multiple graphs of any natural multiplicity $k>1$. There are edges of three types: ordinary edges, multiple edges and multi-edges. Each edge of the last two types is a union of $k$ linked edges, which connect 2 or $(k+1)

The Modified Rural Postman Problem in Vehicle Route Optimization
Communications, 2018 The submitted paper deals with designing routes of the vehicles, which provide the transport network services. We limit our focus to such tasks, where the priority is the edge service in the transport network and the initial problem is finding an ...

Multi-directed Eulerian growing networks [PDF]
, 2007 We introduce and analyze a model of a multi-directed Eulerian network, that is a directed and weighted network where a path exists that passes through all the edges of the network once and only once.

Warm and moist air intrusions into the winter Arctic: a Lagrangian view on the near-surface energy budgets [PDF]
Atmospheric Chemistry and Physics, 2022 In this study, warm and moist air intrusions (WaMAIs) over the Arctic Ocean sectors of Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, Chukchi Sea, and Beaufort Sea in 40 recent winters (from 1979 to 2018) are identified from the ERA5 reanalysis ...

Finding Even Subgraphs Even Faster [PDF]
, 2014 Problems of the following kind have been the focus of much recent research in the realm of parameterized complexity: Given an input graph (digraph) on $n$ vertices and a positive integer parameter $k$, find if there exist $k$ edges (arcs) whose deletion ...

Steinitz Theorems for Orthogonal Polyhedra [PDF]
, 2009 We define a simple orthogonal polyhedron to be a three-dimensional polyhedron with the topology of a sphere in which three mutually-perpendicular edges meet at each vertex.
