The web is a huge repository of information which needs for accurate automated classifiers for Web pages to maintain Web directories and to increase search engines‟ performance. In web page classification problem each term in each HTML/XML tag of each Web page can be taken as a feature, an efficient methods to select best features to reduce feature space of the Web page classification problem d...

The shear strength of fiber-reinforced polymer (FRP) reinforced concrete beams is often given a large safety margin by current construction requirements. Six characteristics are utilized as inputs to compute the FRP-reinforced beams. This study uses 198 samples from literature predict 139 training and 59 testing samples. Additionally, ANN structure optimized with firefly algorithm. FA-ANN model...

Bio inspiration is a branch of artificial simulation science that shows pervasive contributions to variety of engineering fields such as automate pattern recognition, systematic fault detection and applied optimization. In this paper, a new metaheuristic optimizing algorithm that is the simulation of “The Great Salmon Run” (TGSR) is developed. The obtained results imply on the acceptable perfor...

The structure of the community is one of the important features of social networks. A community is a sub graph which nodes have a lot of connections to nodes of inside the community and have very few connections to nodes of outside the community. The objective of community detection is to separate groups or communities that are linked more closely. In fact, community detection is the clustering...

In this paper, an improved firefly algorithm (FA) was proposed for application on photovoltaic module arrays (PVMAs) with partial modules under shading so that the maximum power point tracking (MPPT) could be implemented. Firstly, a new model of high voltage step-up converter developed executing MPPT PVMA. For energy storage inductor converter, architecture coupled adopted switch did not need t...

This paper presents an improved version of the firefly algorithm (FA) by which a maximum power point (MPP) tracker was developed to track down global (GMPP) partially shaded photovoltaic module array (PVMA). As first step, our team high-voltage step-up converter where coupled inductor used store energy so that duty cycle can be reduced as raise voltage gain. The single-peaked P-V output charact...

This article compares the original firefly-Inspired algorithm (FA) against two versions suggested by the authors. It was found that by using some modifications proposed in this document, the convergence time of the algorithm is reduced, while increasing its precision (i.e. it is able to converge with less error). Thus, it is strongly recommended that these variants are further analyzed, especia...

The image enhancement methods play an important role in digital processing. And by using a different kinds of techniques, such as artificial intelligence techniques methods. aim this is to enhance the visual appearance and reduce noise. In paper, corrupted de-noise image, we used swarm optimization algorithms firefly algorithm (FA) also neural network perceptron (PNN). then after added fuzzy me...

As one of the evolutionary algorithms, firefly algorithm (FA) has been widely used to solve various complex optimization problems. However, FA significant drawbacks in slow convergence rate and is easily trapped into local optimum. To tackle these defects, this paper proposes an improved combined with extremal (EO), named IFA-EO, where three strategies are incorporated. First, balance tradeoff ...

Selecting internal hyperparameters, which can be set by the automatic search algorithm, is important to improve generalization performance of machine learning models. In this study, geological, remote sensing and geochemical data Lalingzaohuo area in Qinghai province were researched. A multi-source metallogenic information spatial was constructed calculating Youden index for selecting potential...
