New approach for prediction of asphaltene precipitation due to natural depletion by using evolutionary algorithm concept

► A neural network combine with particle swarm optimization has been presented. ► PSO-ANN model combines local and global searching ability of the ANN and PSO, respectively. ► It has improved the fitting between PSO-ANN prediction of the model and the experimental data. ► The PSO parameters have been carefully designed to optimize the ANN, avoiding premature convergence.
