Problems solved by technology

When the intelligent multi-objective algorithm is used to solve the problem, the solution process is usually lengthy and difficult to integrate into practical engineering applications; while the algorithm that is directly converted to a single object has insufficient diversity in the searched solutions, and it is easy to fall into local optimum and fail to solve the problem. get the Pareto optimal solution
