*4.6. Research Prospects*

The previous section summarizes the challenges in studies, and this section suggests some research directions. They are an essential reference for researchers in developing their plans.

For specific metaheuristics:


Regardless of the specific techniques, any approach to raise the metaheuristics is to employ complementary improvements to balance exploration and exploitation and, ultimately, fit to the studied issue.

In addition to research directions for metaheuristics, some potential directions for application scenarios include the following areas:

1. For the parameter extraction, diminishing computational resources' consumption is at stake. Reducing TNFES while maintaining the same accuracy by introducing different techniques, i.e., local search and reinforcement learning, is a direction worthy of further research.
