This paper proposes a modified sine cosine algorithm (MSCA) for discrete sizing optimization of truss structures. The original sine cosine algorithm (SCA) is a population-based metaheuristic that fluctuates the search agents about the best solution based on sine and cosine functions. The efficiency of the original SCA in solving standard optimization problems of well-known mathematical function...

Colliding Bodies Optimization (CBO) is a population-based metaheuristic algorithm that complies physics laws of momentum and energy. Due to the stagnation susceptibility of CBO by premature convergence and falling into local optima, some meritorious methodologies based on Sine Cosine Algorithm and a mutation operator were considered to mitigate the shortcomings mentioned earlier. Sine Cosine Al...

This paper is associated with implementation of Sine & Cosine using Volder’s CORDIC Algorithm. CORDIC algorithm based Systems are used for fast and silicon area efficient computation of the sine and cosine functions. The algorithmic approach for the CORDIC algorithm implementation is presented here. Summary of CORDIC synthesis results based on Actel and XILINX FPGAs is given. Finally applicatio...

Abstract In many real-world situations, we have to deal with multiple objectives simultaneously in order make appropriate decisions. The presence of an optimization problem makes the challenging because most time these are conflicting nature. For example, may want maximize return on investment a portfolio and, other hand, minimize risk associated assets portfolio. We cost product while maximizi...

1 Abstract This paper describes the design and simulation of an 8-bit dedicated processor for calculating the Sine and Cosine of an Angle using CORDIC Algorithm (COordinate Rotation DIgital Computer), a simple and efficient algorithm to calculate hyperbolic and trigonometric functions. We have proposed a dedicated processor system, modeled by writing appropriate programs in VHDL, for calculatin...

The paper presents the implementation and an analysis of the Jordan's nonparametric curve generator algorithm in H/W acceleration solutions like sine/cosine generation. It is shown that the x and y coordinate sequences generated by the algorithm as the curve representation are really approximated nonuniform sampled cosine/sine functions sequences of values with useful properties. The nonuniform...

The paper provides a full self-contained derivation of fast algorithms to compute discrete Cosine and Sine transforms I IV. For the Sine I/II and Cosine I/II transforms a unified derivation based on the concept of the comrade matrix is presented. The comrade matrices associated with different versions of the transforms differ in only a few boundary elements; hence, in each case algorithms can b...
