Abstract

If  is continuous and nonlinear on , its application has proven evident throughout time. Minimizers are points where  is not differentiable. This work specifically focuses on the scenario when it is challenging to calculate the gradient and Hessian matrices for each given value of . This study introduces a novel technique that utilizes derivatives to solve optimization problems. Specifically, it focuses on employing finite difference representations of the gradient and Hessian in the Quasi Newton method and Derivative Free Trust Region methods. If it is proven that  has a unique solution, it may be demonstrated that the step length ( ) generated converges globally. Two test problems were employed for actual implementation utilizing MATLAB software. The numerical outcomes demonstrated the efficacy and resilience of the algorithms, which exhibited favourable comparisons to certain preexisting methods.
