3. Description of the methodology for estimating parameters
>For the estimation of thermodynamic parameters it is necessary to define a performance criterion, that is, an objective function (error criterion to be minimized) and an optimization method. Depending on the chosen error criterion, a specific method can be selected by the modeler for optimization. In this paper we compared two error criteria (sum of square error and maximum error in absolute value), with two different initialization procedures; the first considers only a random initial guess in the space of the search (called "simple procedure), and the other initialization process is based on the division of the error surface in different regions. The error surface was described in Part I of this series. The initial guess, Based off the knowledge of the most region where the global optimum can be found, called "specialized initialization
