Direct Acyclic Graph or DAG may be it. What is DAG? DAG is a directed graph data structure that uses a topological ordering. The sequence can only go from earlier to later.

As we continue moving toward mass adoption, directed acyclic graphs certainly show some promise in addressing the nagging issue of scalability.

Bitcoin was Blockchain 1.0 and the decentralized Ethereum is Blockchain 2.0 and Blockchain 3.0 could be Direct Acyclic Graph (DAG). In mathematics and computer science, a directed acyclic graph, is a ...

Tangle is the distributed ledger for the cryptocurrency network IOTA. Instead of a linear block system like a blockchain, it uses a direct acyclic graph architecture.

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 ...

The PC-algorithm was shown to be a powerful method for estimating the equivalence class of a potentially very high-dimensional acyclic directed graph (DAG) with the corresponding Gaussian distribution ...
