Dynamic Graphs on the GPU [PDF]

open access: yes, 2020
We present a fast dynamic graph data structure for the GPU. Our dynamic graph structure uses one hash table per vertex to store adjacency lists and achieves 3.4–14.8x faster insertion rates over the state of the art across a diverse set of large datasets,

Evaluating the Systemic Importance of China’s Banks via Adjacency Information Entropy

open access: yesDiscrete Dynamics in Nature and Society, 2022
Information entropy can be utilized to assess the complexity of the Banking System and the uncertainty of association information between banks. Based on information entropy and the balance sheet data of 167 banks from 2011 to 2020, we proposed a ...

Spectral Graph Embedding for Dimension Reduction in Financial Risk Assessment [PDF]

open access: yesMathematics and Modeling in Finance, 2021
The economic downturn in recent years has had a significant negative impact on corporates performance. In the last two years, as in the last years of 2010s, many companies have been influenced by the economic conditions and some have gone bankrupt.

Storage method of multi-channel lidar data based on tree structure

open access: yesScientific Reports, 2022
The multi-channel lidar has fast acquisition speed, large data volume, high dimension, and vital real-time storage, which makes it challenging to be met using the traditional lidar data storage methods. This paper presents a novel approach to storing the

Complementary vertices and adjacency testing in polytopes [PDF]

open access: yes, 2012
Our main theoretical result is that, if a simple polytope has a pair of complementary vertices (i.e., two vertices with no facets in common), then it has at least two such pairs, which can be chosen to be disjoint. Using this result, we improve adjacency

Modeling and Planning Multimodal Transport Paths for Risk and Energy Efficiency Using AND/OR Graphs and Discrete Ant Colony Optimization

open access: yesIEEE Access, 2020
Path sequence selection is important for multimodal transport processes. AND/OR graphs (AOG) have been applied to describe practical multimodal transport route planning problems by using ‘AND’ and ‘OR’ matrices.

A linear algorithm for the restricted subtraction games

open access: yesFrontiers in Physics, 2022
The subtraction game is a well-known problem in the field of game theory, which is often called a one-heap Nim game. There are two players, a heap of tokens, and a strategy matrix, in this game.
