Image segmentation is applied widely to image processing and object recognition. Threshold segmentation is a simple and important method in grayscale image segmentation. Information entropy can characterize the grayscale in formation of image and distinguish between the objectives and background. In this paper, we use exponential entropy instead of logarithmic entropy and propose a new multilev...
this paper proposes a novel hybrid algorithm namely apso-bfo which combines merits of bacterial foraging optimization (bfo) algorithm and adaptive particle swarm optimization (apso) algorithm to determine the optimal pid parameters for control of nonlinear systems. to balance between exploration and exploitation, the proposed hybrid algorithm accomplishes global search over the whole search spa...

A new adaptive hybrid optimization strategy, entitled squads, is proposed for complex inverse analysis of computationally intensive physics-based models. Typically, models are calibrated and model parameters are estimated by minimization of the discrepancy between model simulations characterizing the system and existing observations requiring a substantial number of model evaluations. Squads is...
کاربرد سیستم های کنترل نیمه فعال به دلایل سادگی و دارا بودن هم زمان مزایای سیستم های کنترل غیر فعال و فعال، روز به روز درحال افزایش و پیشرفت است. در خلال این پیشرفت ها الگوریتم های مختلفی جهت بهینه سازی پاسخ های سازه ها ایجاد شده اند. در این تحقیق به بررسی کنترل نیمه فعال بهینه سازه های برشی مجهز به میراگر mr پرداخته شده است. یکی از عوامل موثر در مقدار نیروی کنترل ایجاد شده، ولتاژ ورودی به میرا...
Metaheuristic algorithm is one of the most popular methods in solving many optimization problems. This paper presents a new hybrid approach comprising of two natures inspired metaheuristic algorithms i.e. Cuckoo Search (CS) and Accelerated Particle Swarm Optimization (APSO) for training Artificial Neural Networks (ANN). In order to increase the probability of the egg’s survival, the cuckoo bird...
In this paper, we formulate the dynamics and philosophy of Quantum-behaved Particle Swarm Optimization (QPSO) Algorithm, and suggest a parameter control method based on the whole population level. After that we introduce a diversity-guided model into the QPSO to make the PSO system an open evolutionary particle swarm and therefore propose the Adaptive Quantum-behaved Particle Swarm Optimization...

To address the problems of 5G network planning and optimization, a user time delay prediction model based on BiLSTM neural optimized by APSO-SD is proposed. First, channel generative ray-tracing statistical constructed to obtain large amount data, ray data feature three-dimensional stereo mapping proposed for input extraction. Then, an adaptive particle swarm optimization algorithm search pertu...
