A directed acyclic graph for interactions [PDF]

open access: yesInternational Journal of Epidemiology, 2020
Abstract Background Directed acyclic graphs (DAGs) are of great help when researchers try to understand the nature of causal relationships and the consequences of conditioning on different variables.

Cycle analysis of Directed Acyclic Graphs

open access: yesPhysica A: Statistical Mechanics and Its Applications, 2022
In this paper, we employ the decomposition of a directed network as an undirected graph plus its associated node metadata to characterise the cyclic structure found in directed networks by finding a Minimal Cycle Basis of the undirected graph and augment its components with direction information. We show that only four classes of directed cycles exist,

Multilevel Algorithms for Acyclic Partitioning of Directed Acyclic Graphs [PDF]

open access: yesSIAM Journal of Scientific Computing, 2019
Summary: We investigate the problem of partitioning the vertices of a directed acyclic graph into a given number of parts. The objective function is to minimize the number or the total weight of the edges having end points in different parts, which is also known as the edge cut. The standard load balancing constraint of having an equitable partition of

Design and Implementation of Solution Algorithm for Foreign Key Conflict Based on Directed Graph [PDF]

open access: yesJisuanji gongcheng, 2021
As one of the important constraints in relational databases,foreign keys play an important role in constraining the order of operations of the database.However,in some cases,users cannot know the order of operations,causing foreign key conflicts.To solve

Survey of Directed Acyclic Graph Based Blockchain Technology [PDF]

open access: yesJisuanji gongcheng, 2022
Blockchain technology has been widely used in finance, public services, the Internet of Things(IoT), network security, supply chains, and other fields.However, the traditional blockchain with a single chain structure has some deficiencies in throughput ...

Fuzzing Test Case Generation Method Based on Depth-first Search [PDF]

open access: yesJisuanji kexue, 2021
Fuzzing test is an important method to exploit network protocol vulnerability.Existing fuzzing test methods have some problems such as incomplete path coverage and low efficiency.To solve these problems,this paper proposes a depth-first search based ...

Directed Acyclic Graphs With Tears

open access: yesIEEE Transactions on Artificial Intelligence, 2023
Bayesian network is a frequently-used method for fault detection and diagnosis in industrial processes. The basis of Bayesian network is structure learning which learns a directed acyclic graph (DAG) from data. However, the search space will scale super-exponentially with the increase of process variables, which makes the data-driven structure learning

Acyclic Partitioning of Large Directed Acyclic Graphs [PDF]

open access: yes2017 17th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGRID), 2017
Finding a good partition of a computational directed acyclic graph associated with an algorithm can help find an execution pattern improving data locality, conduct an analysis of data movement, and expose parallel steps. The partition is required to be acyclic, i.e., the inter-part edges between the vertices from different parts should preserve an ...
