Implement a new optimization algorithm

[heyu]

Hello, I am a student using FEniCS. I hope to use FEniCS to implement a new optimization algorithm. I hope to use the deep reinforcement learning method to replace the adjoint method to optimize the shape, but I encountered difficulties in implementing this code.
I hope to optimize some parameters through deep reinforcement learning, and then use the parameters to change the shape of the mesh. But the ALE method in FEniCS needs to solve the entire mesh area. I hope to change the shape of the mesh through some scalar parameters, which are easy to obtain and change. Those parameters may be an array. Can you give some advice? Is there such a scalar parameter in FEniCS that allows me to easily change the mesh shape? Thank you for your help.
