Synchronizing a virtual cellular automaton collider
Oswaldo L. Barrientos;Genaro J. Martínez;Andrew Adamatzky;Shigeru Ninagawa
Publication Year: 2022,Page(s):1 - 10
Cellular automata have been a topic of great interest in unconventional computation theory for its architecture: simple but capable of producing complex structures with a dynamic behavior and massive parallel computation. Collision-based computing with multiple reactions is a way to explore such capacities. Following this logic, a virtual collider was proposed as a way to develop computers by usin...Show More
Accelerating Numerical Inverse Kinematics Methods with the Lookup Table
Publication Year: 2022,Page(s):11 - 18
Inverse kinematics (IK) for a robotic arm solves for the joint variables to move its end-effector to a target position with an optional orientation. IK can be solved by iterative numerical methods. However, as the degree-of-freedom (DoF) of the robotic arm increases or the applications impose extra constraints, the iterative process will be lengthened dramatically. In this paper, we study the idea...Show More
A Recurrence for the Surface Area of the ($n, k$)-Star Graph
Publication Year: 2022,Page(s):19 - 26

Publication Year: 2022,Page(s):36 - 45
Cited by: Papers (3)
We propose COFFEE, a Content Oriented Flexible Framework with Egress Engineering, improving client QoE in content delivery. BGP lacks visibility into performance, so they do not know which path maximizes the QoE of their content. COFFEE engineers egress paths based on the strategies formulated by content operators. Thus, it realizes performance-aware routing that reflects the characteristics of ea...Show More

Publication Year: 2022,Page(s):66 - 75
Cited by: Papers (1)
Natural Gradient Descent (NGD) is a second-order neural network training that preconditions the gradient descent with the inverse of the Fisher Information Matrix (FIM). Although NGD provides an efficient preconditioner, it is not practicable due to the expensive computation required when inverting the FIM. This paper proposes a new NGD variant algorithm named Component-Wise Natural Gradient Desce...Show More
Dynamic Group Signatures with Message Dependent Opening and Non-Interactive Signing
Publication Year: 2022,Page(s):76 - 82
Cited by: Papers (2)
The group signature with message dependent opening (GS-MDO) is a valiant of the group signature in a sense that the opening authority is split into two parties called the opener and the admitter. Most known constructions of GS-MDO employ the static model. The only scheme using the dynamic model by Sun and Liu has a problem on the anonymity against the admitter in the real-world usage because the s...Show More

AI engines utilizing deep learning neural networks provide excellent tools for analyzing traditional board games. Here we are interested in gaining new insights into the ancient game of Go. For that purpose, we need to define new numerical measures based on the raw output of the engines. In this paper, we develop a numerical tool for automated move-by-move performance evaluation in a context-sensi...Show More
In photography, bokeh is the aesthetic effect appearing in out-of-focus areas. Bokeh is often used to emphasize a subject or to express a beautiful background. However, such bokeh effects can be expressed with cameras equipped with large-aperture lenses but are not easy to realize with small-aperture lenses. The main contribution of this paper is to propose a technique to generate a bokeh image fr...Show More

The most efficient method for solving ECDLP is the Pollard-Rho method, which is known to be more efficient in solving ECDLP by using skew Frobenius mapping and splitting a seed-point table to eliminate the fruitless cycles, but some fruitless cycles increase non-negligibly. In this paper, we propose a method to further reduce the number of fruitless cycles in the Pollard's rho method using skew Fr...Show More
