A Directed Acyclic Graph is a data structure that consists of nodes connected by directed edges, where each node has one or more parents. Importantly, there are no cycles in a DAG, meaning there ...

Bitcoin’s rise into popularity resulted in it being categorized as Blockchain 1.0. With Ethereum making waves, more and more people began to categorize Ethereum as Blockchain 2.0. Now the market ...

In mathematics and computer science, a directed acyclic graph, is a finite directed graph with no directed cycles. It consists of finitely many vertices and edges, with each edge directed from one ...

Let’s talk about directed acyclic graphs, or DAGs. A DAG protocol is an alternative to the traditional blockchain and can be categorized as a distributed ledger technology.

AbstractFor a non-trivial connected graph 𝐺, a set 𝑆 ⊆ 𝑉 (𝐺) is called an edge geodetic set of 𝐺 if every edge of 𝐺 is contained in a geodesic joining some pair of vertices in 𝑆. The edge ...

Collapsibility means that the same statistical result of interest can be obtained before and after marginalization over some variables. In this paper, we discuss three kinds of collapsibility for ...
