The purpose of proving recursion relations in BFGS non linear optimization is to find an efficient and accurate way to update the Hessian matrix in order to improve the convergence rate of the optimization algorithm. Recursion relations provide a systematic way to update the Hessian matrix without the need for expensive computations.
The BFGS algorithm is a quasi-Newton method used for solving non linear optimization problems. It is an iterative method that uses an approximation of the Hessian matrix to find the minimum of a non linear objective function. The BFGS algorithm aims to improve the convergence rate of the optimization process by updating the Hessian matrix at each iteration.
Recursion relations are mathematical equations that define a sequence of values in terms of previous values. In BFGS optimization, recursion relations are used to update the Hessian matrix based on the gradient of the objective function at each iteration. This allows for a more efficient and accurate update of the Hessian matrix compared to re-computing it from scratch.
To prove recursion relations in BFGS non linear optimization, one must use mathematical induction. This involves showing that the recursion relation holds for the first few values, and then assuming it holds for a general value and proving it holds for the next value in the sequence. This process is repeated until the relation is proven to hold for all values.
Using recursion relations in BFGS non linear optimization has several benefits. First, it allows for a more efficient and accurate update of the Hessian matrix, leading to faster convergence of the optimization algorithm. Additionally, recursion relations can be easily implemented in computer programs, making them a practical choice for optimization problems in real-world applications.
