Generalized shortest path kernel on graphs

L Hermansson, FD Johansson, O Watanabe - Discovery Science: 18th …, 2015 - Springer
We consider the problem of classifying graphs using graph kernels. We define a new graph
kernel, called the generalized shortest path kernel, based on the number and length of …

ASP-Completeness of Hamiltonicity in Grid Graphs, with Applications to Loop Puzzles

J Brunner, L Chung, ED Demaine… - … Conference on Fun …, 2024 - drops.dagstuhl.de
We prove that Hamiltonicity in maximum-degree-3 grid graphs (directed or undirected) is
ASP-complete, ie, it has a parsimonious reduction from every NP search problem (including …

The Fine-Grained Complexity of Approximately Counting Proper Connected Colorings

RD Barish, T Shibuya - International Conference on Combinatorial …, 2023 - Springer
A k-proper connected 2-coloring for a graph is an edge bipartition which ensures the
existence of at least k vertex disjoint simple alternating paths (ie, paths where no two …

The complexity of counting models of linear-time temporal logic

H Torfah, M Zimmermann - Acta Informatica, 2018 - Springer
We determine the complexity of counting models of bounded size of specifications
expressed in linear-time temporal logic. Counting word-models is# P-complete, if the bound …

Computing permanents and counting hamiltonian cycles by listing dissimilar vectors

A Björklund, R Williams - 46th International Colloquium on …, 2019 - drops.dagstuhl.de
We show that the permanent of an nxn matrix over any finite ring of r<= n elements can be
computed with a deterministic 2^{n-Omega (n/r)} time algorithm. This improves on a Las …

Pentagonal chains and annuli as models for designing nanostructures from cages

VR Rosenfeld, AA Dobrynin, JM Oliva, J Rue - Journal of mathematical …, 2016 - Springer
Carbon is the most versatile of chemical elements in combining with itself or other elements
to form chains, rings, sheets, cages, and periodic 3D structures. One of the perspective …

Some observations on holographic algorithms

LG Valiant - computational complexity, 2018 - Springer
We define the notion of diversity for families of finite functions and express the limitations of a
simple class of holographic algorithms, called elementary algorithms, in terms of limitations …

Calculating the number of Hamilton cycles in layered polyhedral graphs

LN Wirz, P Schwerdtfeger… - … and Mathematical Methods, 2021 - Wiley Online Library
We describe a method for computing the number of Hamilton cycles in cubic polyhedral
graphs. The Hamilton cycle counts are expressed in terms of a finite‐state machine, and can …
