The author studies the inverse one phase Stefan problem and proves that under some conditions this problem is approximately solvable in a certain sense. The key idea of the proof is to approximate the inverse Stefan problem by an appropriate optimal control problem, which represents a parabolic boundary problem and can be then investigated by using the standard Sobolev space technique.
