Price simulation and prediction of leaf vegetable based on gene expression algorithm

Based on the traditional gene expression algorithm, the paper proposed an improved gene expression algorithm, adding "inverted string" and "gene extraction" operator. An improved GEP algorithm is used in the leafy vegetables prices forecast, create the mathematical model through the analysis and evolution of training data, realize the simulation and forecast of the price of leafy vegetables. Through several experiments, the results proved that the new type of gene expression programming algorithm has faster convergence rate and higher precision in predicting the price of leafy vegetables.
