Abstract
A numerical algorithm for the estimation of unknown parameters in the multidimensional Stefan problem is described. The moving boundary is treated as an additional unknown parameter, rather than as a dynamic state of the system. A similar algorithm has been tested for the one-dimensional Stefan problem and appears to be robust under noisy observations. A convergence result is stated, and results for a simpler numerical example are presented
