WebTo tackle this issue, this paper proposes a homotopy Strategy based on the Relaxation of the dynamic constraints of the optimization problem. The relaxed problem differs from the original one only by a single parameter, which is gradually modified to obtain the solution to the original problem. 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.
