"WebMar 7, 2024 · The Landweber iteration or Landweber algorithm is an algorithm to solve ill-posed linear inverse problems, and it has been extended to solve non-linear problems that involve constraints. The method was first proposed in the 1950s by Louis Landweber, [1] and it can be now viewed as a special case of many other more general methods. " - Relaxation strategy for the landweber method
