The aim of this work was to study the application of a stochastic algorithm to correlate the experimental data of island-type systems in ternary systems. Thermodynamic NRTL and UNIQUAC models were used to evaluate the activity coefficients. Results regarding the application of the stochastic algorithm were in good agreement with those presented in the current literature. However, generalization of the method proposed in the present work remained an intriguing and complex task so as to reach broad conclusions.
