Edge-Constrained Hamiltonian Paths on a Point Set
Todor Antić, Aleksa Džuklevski, Jiří Fiala +5
Let S be a set of distinct points in general position in the Euclidean plane. A plane Hamiltonian path on S is a crossing-free geometric path such that every point of S is a vertex…

Computational complexity of covering regular trees
Jan Bok, Jiří Fiala, Nikola Jedličková +1
A graph covering projection, also referred to as a locally bijective homomorphism, is a mapping between the vertices and edges of two graphs that preserves incidences and is a loca…

Computational Complexity of Covering Colored Mixed Multigraphs with Simple Degree Partitions
Jan Bok, Jiří Fiala, Nikola Jedličková +2
The notion of graph covers (also referred to as locally bijective homomorphisms) plays an important role in topological graph theory and has found its computer science applications…
