circuit_optimization_gnn_ppo_masked

Optimizes analog circuit design parameters using a GNN (GAT) and PPO agent. Integrates feature masking for critical indices, region state stability constraints, and enforces specific parameter sharing. Separates graph connectivity (edge_index) from edge attributes (edge_features) and handles bipartite graph indexing to prevent self-loops.
