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.
