  Options: | eps : float Step size used for numerical approximation of the jacobian. scale : list of floats Scaling factors to apply to each variable. If None, the factors are up-low for interval bounded variables and 1+|x] fo the others. Defaults to None offset : float Value to subtract from each variable. If None, the offsets are (up+low)/2 for interval bounded variables and x for the others. disp : bool Set to True to print convergence messages. maxCGit : int Maximum number of hessian*vector evaluations per main iteration. If maxCGit == 0, the direction chosen is -gradient if maxCGit < 0, maxCGit is set to max(1,min(50,n/2)). Defaults to -1. maxiter : int Maximum number of function evaluation. if None, maxiter is set to max(100, 10*len(x0)). Defaults to None. eta : float Severity of the line search. if < 0 or > 1, set to 0.25. Defaults to -1. stepmx : float Maximum step for the line search. May be increased during call. If too small, it will be set to 10.0. Defaults to 0. accuracy : float Relative precision for finite difference calculations. If <= machine_precision, set to sqrt(machine_precision). Defaults to 0. minfev : float Minimum function value estimate. Defaults to 0. ftol : float Precision goal for the value of f in the stoping criterion. If ftol < 0.0, ftol is set to 0.0 defaults to -1. xtol : float Precision goal for the value of x in the stopping criterion (after applying x scaling factors). If xtol < 0.0, xtol is set to sqrt(machine_precision). Defaults to -1. gtol : float Precision goal for the value of the projected gradient in the stopping criterion (after applying x scaling factors). If gtol < 0.0, gtol is set to 1e-2 * sqrt(accuracy). Setting it to 0.0 is not recommended. Defaults to -1. rescale : float Scaling factor (in log10) used to trigger f value rescaling. If 0, rescale at each iteration. If a large value, never rescale. If < 0, rescale is set to 1.3.
