Gold is a precious metal often used for investment, due to its cash-in ease and yearly value increase. This indicates that price forecasting determine the prospect of future gold prices. Strong highly desired by investors make decisions. That why technical indicators are very important forecasting. By using information obtained can be more informative than pure One commonly methods Backpropagat...

The metaheuristic optimization algorithm Harmony search (HS), which imitates the process of music improvisation, is becoming widely used due to its simplicity and easy operation. However, basic HS has shortcomings low accuracy risk falling into local optimum. To overcome these problems, this article develops an ameliorated harmony with hybrid convergence mechanism, namely AHS-HCM. For new metho...

Wireless Sensor Networks are the new generation of networks that typically are formed great numbers of nodes and the communications of these nodes are done as Wireless. The main goal of these networks is collecting data from neighboring environment of network sensors. Since the sensor nodes are battery operated and there is no possibility of charging or replacing the batteries, the lifetime of ...

Clustering has become an increasingly important and highly complicated research area for targeting useful and relevant information in modern application domains such as the World Wide Web. Recent studies have shown that the most commonly used partitioning-based clustering algorithm, the K-means algorithm, is more suitable for large datasets. However, the K-means algorithm may generate a local o...

Being one of the main challenges to clustering algorithms, the sensitivity of fuzzy c-means (FCM) and hard c-means (HCM) to tune the initial clusters centers has captured the attention of the clustering communities for quite a long time. In this study, the new evolutionary algorithm, Harmony Search (HS), is proposed as a new method aimed at addressing this problem. The proposed approach consist...

When musicians compose the harmony, they usually try various possible combinations of the music pitches stored in their memory, which can be considered as a optimization process of adjusting the input (pitches) to obtain the optimal output (perfect harmony). Harmony search draws the inspiration from harmony improvisation, and has gained considerable results in the field of optimization, althoug...

In recent years, distributed generation (DG) has become more common in modern distribution networks (DNs). The presence of these small-scale units within a DN brings new challenges to protection engineers, since short-circuit currents tend increase; additionally, as with microgrids, DNs may feature several operational modes depending on their topology and the availability DG. This paper present...

In this study, the tuned liquid damper (TLD) device was optimized by harmony search (HS) and adaptive algorithms (AHS). Using algorithm, seismic excitations were directed at single ten-story structures, TLD parameters to minimize building movement. To improve design parameters, optimization process repeated adapting factors of algorithm. For purpose, both memory consideration ratio (HMCR) fret ...
