Struct argmin::solver::landweber::Landweber[][src]

pub struct Landweber<F> { /* fields omitted */ }

The Landweber iteration is a solver for ill-posed linear inverse problems.

In iteration k, the new parameter vector x_{k+1} is calculated from the previous parameter vector x_k and the gradient at x_k according to the following update rule:

x_{k+1} = x_k - omega * \nabla f(x_k)
