Algorithms

  1. DQN: Deep Q-learning (double & dueling network)
  2. IQL: Independent Q-learning
  3. VDN: Value Decomposition Network
  4. QMIX: Monotonic Value Function Factorisation
  5. A2C & MAA2C: advantage actor-critic
  6. PPO & MAPPO:
  7. Behavior Cloning (demo)
  8. GAIL (demo): Generative adversarial imitation learning

Tricks

  • Multiple input & Multiple output: Used in DQN when if_mac == True
  • Recurrent network (demo): if_recurrent DRQN
    • Use GRU to deal with timeseries data
  • Graph convolution network (demo): global_state
    • Info of all the elements (nodes or links)
    • Use GCN to convolve before MLP
    • Share convolution layers: share_conv_layer

Requirements

  • tensorflow >= 2.3
  • tensorflow_probability >= 0.11.1
  • spektral == 1.2.0
  • pyswmm >= 0.6.2
  • pystorms >= 1.0.0
  • swmm-api == 0.2.0.18
  • pymoo == 0.6.0
