Electrical Department, V.J.T.I. Mumbai Abstract In recent researches, there are countless applications where sine and cosine wave are used, like in Physics, Digital Signal Processing for various transforms, several modulation and demodulation techniques etc. There are numerous ways to generate digital sine and cosine waves, the use of previously calculated tables is one of the choices, but it r...

Economic load dispatch (ELD) provides significant benefits to the operation of power system. It appears be a complex nonconvex optimization problem subject several equal and unequal constraints. The greedy sine-cosine nonhierarchical gray wolf optimizer (G-SCNHGWO) is introduced in this study solve ELD problems efficiently robustly. sine cosine functions assist search agents grey (GWO) algorith...

We derive a new algorithm for computing the action f(A)V of the cosine, sine, hyperbolic cosine, and hyperbolic sine of a matrix A on a matrix V , without first computing f(A). The algorithm can compute cos(A)V and sin(A)V simultaneously, and likewise for cosh(A)V and sinh(A)V , and it uses only real arithmetic when A is real. The algorithm exploits an existing algorithm expmv of Al-Mohy and Hi...

This study introduces an effective hybrid optimization algorithm, namely Particle Swarm Sine Cosine Algorithm (PSSCA) for numerical function and automating optimum design of retaining structures under seismic loads. The new algorithm employs the dynamic behavior sine cosine functions in velocity updating operation particle swarm (PSO) to achieve faster convergence better accuracy final solution...

The goal was to address the problems of slow convergence speed, low solution accuracy and insufficient performance in solving complex functions search process an arithmetic optimization algorithm (AOA). A multi-strategy improved (SSCAAOA) is suggested this study. By enhancing population’s initial distribution, optimizing control parameters, integrating positive cosine with adding inertia weight...
