This final project discusses a hybrid method for solving a system of nonlinear equations called the Jarratt Butterfly Optimization Algorithm (JBOA). This method combines the Jarratt iteration method with the Butterfly Optimiza- tion Algorithm (BOA) to improve accuracy and convergence speed, avoiding singularity, as well to reduce the likelihood of getting trapped in local solu- tions, which is …
This final project discusses a family of iterative method using weight functions to solve nonlinear equations. Convergence analysis using Taylor expansion and geometric series shows that this iterative method have fifth-order convergence. This family is highly flexible due to its form and the diverse choice of weight functions, which allows it to generate various new specific schemes. It also i…
