Conjugate Gradient Methods

Algorithm

Conjugate Gradient Methods represent a class of iterative techniques primarily employed for solving systems of linear equations, particularly those arising from optimization problems within quantitative finance. Their application extends to minimizing quadratic functions, a common task in portfolio optimization, risk management, and option pricing models. Within cryptocurrency derivatives, these methods offer a computationally efficient alternative to direct solvers, especially when dealing with high-dimensional problems inherent in complex pricing models or calibration exercises. The core principle involves minimizing the residual error at each iteration, leveraging previously computed search directions to accelerate convergence towards the optimal solution.
