    Summary: We present an improved method for determining the search direction in the Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm. Our approach uses the equal inner product decomposition method for positive-definite matrices. The decomposition of an approximated Hessian matrix expresses a correction formula that is independent from the exact line search. This decomposed matrix is used to compute the search direction in a new BFGS algorithm.
