Particle swarm optimization based on temporal-difference learning for solving multi-objective optimization problems
Computing - Tập 105 - Trang 1795-1820 - 2023
Multi-objective evolutionary algorithms have become the most important method to deal with multi-objective optimization problems (MOP). To improve the performance of particle swarm optimization (PSO) in addressing MOPs, a multi-objective PSO based on temporal-difference learning (TDLMOPSO) is proposed in this paper. The iteration process of TDLMOPSO is transformed into a Markov decision process, p......
MDER: modified degree with exclusion ratio algorithm for influence maximisation in social networks
Computing - Tập 104 - Trang 359-382 - 2021
The online social network has become an integral part of our day to life and serves as an excellent platform for sharing ideas, opinions, and products. Influence maximization (IM) is a widely studied topic in the area of social network analysis. The objective of IM is to find influential nodes that can disseminate information to a larger extent in the network. Many local and global centrality meas......
A second order monotone upwind scheme
Computing - Tập 36 - Trang 57-67 - 1986
We analyze a special finite difference scheme of upwind type for an ordinary singularly perturbed nonlinear boundary value problem. In particular we prove the uniqueness and monotone dependence upon the right hand sides of the discrete solutions and the second order accuracy in the global domain.
Distribution of Lattice Points
Computing - Tập 78 - Trang 173-193 - 2006
We discuss the lattice structure of congruential random number generators and examine figures of merit. Distribution properties of lattice measures in various dimensions are demonstrated by using large numerical data. Systematic search methods are introduced to diagnose multiplier areas exhibiting good, bad and worst lattice structures. We present two formulae to express multipliers producing wors......

Computation of Self-similar Solution Profiles for the Nonlinear Schrödinger Equation
Computing - Tập 77 - Trang 335-346 - 2006
We discuss the numerical computation of self-similar blow-up solutions of the classical nonlinear Schrödinger equation in three space dimensions. These solutions become unbounded in finite time at a single point at which there is a growing and increasingly narrow peak. The problem of the computation of this self-similar solution profile reduces to a nonlinear, ordinary differential equation on an ......
Detecting bad information in mobile wireless networks based on the wireless application protocol
Computing - Tập 96 - Trang 855-874 - 2013
The scale of mobile wireless networks is increasing sharply. However, many websites in the WAP networks contain obscenity information, viruses, and Trojans. How to crawl, judge and locate these bad websites is a challenging problem. In this article, a WAP bad information detection system is proposed, which contains crawling, judgment and location subsystems to identify bad WAP websites. The distri......

Light-weight Synchronous Java (SJL): An approach for programming deterministic reactive systems with Java
Computing - Tập 97 - Trang 281-307 - 2014
A key issue in the development of reliable embedded software is the proper handling of reactive control-flow, which typically involves concurrency. Java and its thread concept have only limited provisions for implementing deterministic concurrency. Thus, as has been observed in the past, it is challenging to develop concurrent Java programs without any deadlocks or race conditions. To alleviate th......
