Research ArticleOpen accessAll words, across the recordA New Spectral Conjugate Gradient Method for Nonlinear Unconstrained OptimizationIbtisam A. Masmali, Zabidin Salleh, Ahmad AlhawaratTheconjugate gradient method is widely used to solve large scale unconstrainedoptimization problems. However, the rate of convergence conjugate gradient method is linearunless it restarted. In this study, we present a new spectral conjugategradient modification formula with restart property obtains the globalconvergence and descent properties.In addition, we proposed a new restart condition for Fletcher-Reeves conjugate gradient formula. The numerical resultsdemonstrated that … …Journal of Computer Science, Vol. 17, Issue 6 · 5 Jul 2021 · 6,653 accessesView PDFCite

In this research, we developed efficient network planning methods for Wireless Interoperability for Microwave Access (WiMAX) networks in which the multiple hops of relay stations are deployed. Approach: An integer linear programming model … …Journal of Computer Science, Vol. 8, Issue 9 · 9 Aug 2012 · 7,459 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Inverse Kinematic Solution of a T4R Robotic ManipulatorShravan Anand KomakulaInverse kinematics has always been a major subject of extensive research filled with redundancy. A need for meticulous functioning and fast computation is always high in any mechatronic system and is growing with new advances and human requirements. In this paper, a T4R (T-Twisting, R-Rotary) robot with constrained motion and joint precision of 1 degree is analyzed for its workspace … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 15 May 2019 · 6,758 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOPTIMIZING LOCALIZATION ROUTE USING PARTICLE SWARM-A GENETIC APPROACHL. Lakshmanan, D. C. TomarOne of the most key problems in wireless sensor networks is finding optimal algorithms for sending packets from source node to destination node. Several algorithms exist in literature, since some are in vital role other may not. Since WSN focus on low power consumption during packet transmission and receiving, finally we adopt by merging swarm particle based algorithm with genetic … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 20 Jan 2014 · 7,381 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAN OPTIMIZATION-BASED HEURISTIC FOR A CAPACITATED LOT-SIZING MODEL IN AN AUTOMATED TELLER MACHINES NETWORKSupatchaya Chotayakul, Peerayuth Charnsetthikul, Juta Pichitlamken, John KobzaThis research studies a cash inventory problem in an ATM Network to satisfy customer’s cash needs over multiple periods with deterministic demand. The objective is to determine the amount of money to place in Automated Teller Machines (ATMs) and cash centers for each period over a given time horizon. The algorithms are designed as a multi-echelon inventory problem with single-item … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 1 Oct 2013 · 7,049 accessesView PDFCite
