In the paper, the inverse problem consisting in the simultaneous estimation of the unknown geometrical parameters of the tumor region based on a local skin surface temperature is solved. The problem of thermal processes proceeding in the domain considered is described by the system of the Pennes equations and boundary conditions given on the outer and contact surfaces. In the stage of numerical solution, the evolutionary algorithm coupled with the multiple reciprocity boundary element method has been applied.
