For example, the current optimal value may be a minimum value among the safety risk values calculated in this embodiment, and the minimum value is recorded as a candidate cost value.
Generally, for the particle swarm optimization algorithm, the current optimal value determined in each iteration needs to be stored in a set buffer so as to determine the final target optimal value. Therefore, the present embodiment stores the candidate cost values and the corresponding candidate parameter values in a setting buffer.
f. Judging whether the set safety risk condition is met or not, if not, executing the step g; if yes, executing step h.
