Sparse storage method for overall design case of solid engine

The invention relates to a sparse storage method for overall design cases of a solid engine, and the method comprises the steps: S1, constructing a prediction agent model for all design cases through employing a radial basis method, and obtaining the initial error values of the prediction agent model for all design cases; s2, obtaining an optimal design case in the design cases; s3, the optimal design case is reserved, an enhanced random evolution algorithm is adopted for experimental design, and center points about all the design cases are obtained; s4, performing clustering processing on all the design cases according to the uniformly distributed center points to obtain a plurality of sample classes; wherein the sample class comprises at least one design case; s5, according to the number of the design cases, sorting the sample classes according to the design cases in a descending order; s6, redundant cases are removed from the sample classes according to the arrangement sequence in the step S5, and sparse d
