PINN for real-world optimization tasks

• To solve real-world optimization tasks, A new type of PINN incorporating "Goal loss" is introduced.
• In this repository, some showcases of optimization tasks (inverting a pendulum, finding the fastest path, and spacecraft swingby) are available, which can be seen in the paper.

Note

• This is a proof-of-concept work, and there still are issues of convergence and seed-dependency. We recommend training on different seeds and choosing the one with the smallest loss, which is still practically reasonable.
• The saved weights and plots are generated with RTX-3080Ti GPU.
