Multi-objective reservoir operation using particle swarm optimization with adaptive random inertia weights

open access: yesWater Science and Engineering, 2020
Based on conventional particle swarm optimization (PSO), this paper presents an efficient and reliable heuristic approach using PSO with an adaptive random inertia weight (ARIW) strategy, referred to as the ARIW-PSO algorithm, to build a multi-objective ...

Particle Convergence Time in the PSO Model with Inertia Weight

open access: yesProceedings of the 7th International Joint Conference on Computational Intelligence, 2015
Particle Swarm Optimization (PSO) is a powerful heuristic optimization method being subject of continuous interest. Theoretical analysis of its properties concerns primarily the conditions necessary for guaranteeing its convergent behaviour. Particle behaviour depends on three groups of parameters: values of factors in a velocity update rule, initial ...

Modified Particle Swarm Optimization using Nonlinear Decreased Inertia Weight

open access: yesEmitter: International Journal of Engineering Technology, 2016
Particle Swarm Optimization (PSO) has demonstrated great performance in various optimization problems. However, PSO has weaknesses, namely premature convergence and easy to get stuck or fall into local optima for complex multimodal problems.

Horizontal Bending Angle Optimization Method for Scraper Conveyor Based on Improved Bat Algorithm

open access: yesAlgorithms, 2019
The horizontal bending angle of scraper conveyor has a great influence on the running resistance, the current consumption, coal winning efficiency of the working surface, etc. Approximately 1–3° is usually the range of horizontal bending angle,

Research on Short-Term Load Forecasting of LSTM Regional Power Grid Based on Multi-Source Parameter Coupling

open access: yesEnergies
Regional power grid load has strong periodicity and randomness, and its load characteristics are affected by many factors. Traditional short-term power load-forecasting methods have certain limitations in accuracy and stability, especially when dealing ...

A Novel Method for Moments of Inertia Tuning for Free-flying Dynamically Similar Models via Simulated Annealing

open access: yesInternational Journal of Technology, 2017
In this study, a method was developed for tuning moments of inertia for a free-flying dynamically similar/scaled model of an aircraft. For this method, the simulated annealing optimization algorithm was used to obtain similar mass-inertial properties of ...
