-r"""
-Our state space comes as:
-$Q_t in R^n$ - our demand at a time t
-$P_t in R^n$ - prices at time t
-$S_t$ some form of interaction session features
-
-This is a single sate which we map under
-
-$f: (Q, S, H) \to P_{t+1}$
-
-With:
-
-$H_t = \{Q_{t-k}, P_{t-k}, S_{t-k}\}$
-
-
-We can have f be literally anything, analytical or learned or rule based or an RL policy.
-
-Our goal is to mazimize the expected revenue:
-
-$E[R_T] = E[\sum_{t=1}^T P_t^T \dot Q_t]$
-
-subject to Q_t = g(P_t, S_t) : demand response to price (estimated via elasticity) and P_t ≥ C : prices above cost floor and additionally minimizing the following:
-
-$L_{agent} = R_{oracle} - R_{observed}
-
-where: R_oracle = revenue if we knew agent intentions (from recon session) and R_observed = revenue under current pricing policy f
-
-I would start be defning a pricing function interface and standardizing how to train that based on historical data and define how to make it behave for online training (if we do that)
-
-We also need to develop a solid benchmark with mapping revenue and full KPIs from session interactions to measure differences between different price learning methods
