Аннотация:For the problem of minimizing functions on a set from Hilbert space specified by equality and inequality constraints, the author proposes a regularized Steffensen method in which the inverse operator of the divided differences is replaced by some approximation of this operator. Conditions on the initial data and matching conditions for the parameters of the method are given which ensure that the method converges strongly to the solution with minimum norm.
