Abstract: Two major milestones on the road to the full complexity dichotomy for finite-domain constraint satisfaction problems were Bulatov’s proof of the dichotomy for conservative templates, and the ...

Introduction: Voxel hierarchy on dynamic brain graphs is produced by k-core percolation on functional dynamic amplitude correlation of resting-state fMRI. Methods: Directed graphs and their ...

At initialisation in both weisfeiler_lehman_graph_hash and weisfeiler_lehman_subgraph_hashes for graphs that do not have node or edge attributes, node weights are initialised using the degree of the ...

The term “blockchain” is so widespread that it’s easy to assume it’s synonymous with distributed ledger technology (DLT). But blockchain is only one type of DLT. Another form of DLT, a Directed ...

The directed acyclic graph (DAG) vs. blockchain debate brings new life to the cryptocurrency industry. Ever since Satoshi Nakamoto first published the Bitcoin (BTC) white paper, distributed ledger ...

ABSTRACT: A vertex cycle cover of a digraph H is a collection C = {C1, C2, …, Ck} of directed cycles in H such that these directed cycles together cover all vertices in H and such that the arc sets of ...
