• Optimal control for state constrained two-phase Stefan problems 

  Neittaanmäki, Pekka; Tiba, Dan (Birkhäuser, 1991)

  We give a new approach to state constrained control problems associated to non-degenerate nonlinear parabolic equations of Stefan type. We obtain uniform estimates for the violation of the constraints.

• A Steepest Descent Method for the Approximation of the Boundary Control in Two-Phase Stefan Problem 

  Neittaanmäki, Pekka; Tiba, D. (Cluj-Napoca : Éditions de l'Académie Roumaine, 1987)

• On the approximation of the boundary control in two-phase Stefan-type problems 

  Neittaanmäki, Pekka; Tiba, D. (Polish Academy of Sciences, 1987)

  The paper is concerned with boundary control of two-phase Stefan problems. A construction of optimal solutions, based on exploiting regularization techniques, is presented. Results of some numerical experiments are discussed.
