 Such algorithms offer the potential for agents to learn bidding strategies in the interplay between market participants.
 In contrast to traditional rule-based approaches, DRL allows for a faster adaptation of the bidding strategies to a changing market
 environment, which is impossible with fixed strategies that a market modeller explicitly formulates. Hence, DRL algorithms offer the

 But without touching the code there are easy adjustments to the algorithms that can and eventually need to be done in the config file.

 The network architecture for the actor in the RL algorithm can be customized by specifying the network architecture used.
 In stablebaselines3 they are also referred to as "policies". The architecture is defined as a list of names that represent the layers of the neural network.
 For example, to implement a multi-layer perceptron (MLP) architecture for the actor, you can set the "actor_architecture" config item to ["mlp"].
 This will create a neural network with multiple fully connected layers.
 
 Other available options for the "policy" include Long-Short-Term Memory (LSTMs). The architecture for the observation handling is implemented from [2].
