Description

The problem of minimization of the functional is considered. A new algorithm is proposed for the solution of these problems. It is based on simultaneous linearization of the experimental constraint functions followed by expression of some variables in terms of others. Expressions for covariance matrix are provided, algorithm for the minimum search is presented. In comparison with the Lagrange multipliers method, this algorithm requires less computation and is applicable to a wider class of problems. 1 ref
