    Application of particle swarm+ant colony optimization to calculate the interaction parameters on phase equilibria

    In this study, a hybrid particle swarm+ant colony optimization (PSO+ACO) was applied to solve the vapor–liquid phase equilibrium. The NRTL activity coefficient model was optimized with this new algorithm and t...
