scipy.optimize.BFGS.
initialize#
- BFGS.initialize(n, approx_type)[source]#
- Initialize internal matrix. - Allocate internal memory for storing and updating the Hessian or its inverse. - Parameters:
- nint
- Problem dimension. 
- approx_type{‘hess’, ‘inv_hess’}
- Selects either the Hessian or the inverse Hessian. When set to ‘hess’ the Hessian will be stored and updated. When set to ‘inv_hess’ its inverse will be used instead.
