A GNN-based Meta-Learning Method for Sparse Portfolio Optimization about evojax HOT 3 OPEN

Hi, thanks for introducing your repo!
I believe these are interesting algos/examples to a wide range of practitioners, and we would love to have your PRs.
As for meta-learning, @LlionJ had this example on locomotion tasks, you may want to have a comparison with his results.

Dear @lerrytang,

I apologize for the rest response. I must have missed the notice. Thanks for referring to @LlionJ's work, I will check in-detail.

I have made a few updates, meanwhile, modified the code for the previous repo shared to perform, for robust optimization (by introducing behavioral diversity), in a noisy reward environment (due to monte-carlo optimization, and action noise/corrupting).

P.S. This basically shows the effectiveness of the optimizer in quality-diversity optimization, on a noisy/stochastic environment.

I also created another repo with examples of solving 100k problems (as well as 500k param MovieLens 1M matrix factorization):
https://github.com/kayuksel/genmeta-vs-nevergrad P.S. This also includes a comparison to Nevergrad on Schwefel 30-dim.

Please let me know if you would have any questions. Have a great week.

Sincerely, Kamer

@LlionJ's weight visualization is similar to my meta-learning method (the heart-beats are exploitation-exploration episodes).
