The target space is equally divided into a plurality of areas by a multi-dimensional stereo grid, and the number of protons contained in each area is used as the density value of the protons. The density value of the proton is larger when the number of protons contained in the grid where the protons are located is larger, and vice versa. If the newly added solution exceeds the boundaries of the current grid, the grid information will be recalculated and each proton will be repositioned. Selecting the position of a first optimal solution according to the obtained internal proton space distribution density; the lower the density value of the spatial distribution of the proton position is, the greater the probability that the proton position is selected, and vice versa.
The selection method of the first optimal solution comprises the following steps: firstly, calculating the number of protons contained in each three-dimensional space grid, taking the number of protons as the density of the grid, and selecting the grid with the lowest density by using a roulette method; a proton position is then randomly selected in this spatial grid as the first optimal solution.
Selecting a second optimal solution for each proton in the internal proton group according to a second optimal solution update strategy, comprising: if the current proton's position is dominated by its second optimal solution, then the second optimal solution is not updated; if the second optimal solution is dominated by the position of the current proton, the position of the current proton replaces the second optimal solution; and if the two solutions are not mutually dominant, randomly selecting one of the solutions as a second optimal solution.
Updating the position of protons in the internal proton group, judging whether a preset stopping criterion (usually set as the maximum iteration number) is reached, and if so, stopping iteration; otherwise, returning to perform network radial check on each proton in the internal proton group.
Preferably, the coded information of the proton code comprises three parts, wherein the first part represents the position of the proton in the search space and has the function of updating the proton group through the position of the proton group and the movement speed of the proton group; the second part represents the position of the protons in the target space, i.e. the value of the respective objective function, whose role is to determine the solution set in the internal proton groups; the third part represents density information of protons, the density information comprises proton density and the number of grids where the protons are located, and the density information is used for selecting a first optimal solution of the protons and deleting redundant protons in the external proton group.
