 Model used for solving Capacitated Vehicle Routing Problem (CVRP). The CVRP is a variant of the vehicle routing problem (VRP) in which vehicles have a limited carrying capacity and must visit a set of customer locations to deliver or collect items.
 Model is based on GitHub repo [HERE](https://github.com/d-eremeev/ADM-VRP), and was used for medium.com article **"Vaccine Supply Chain Optimization with AI-Powered Capacitated Vehicle Routing Problem(CVRP)"**.
 
+**Dynamic Attention Model (AM-D) Approach**:
+After vehicle returns to depot, the remaining nodes could be considered as a new (smaller) instance (graph) to be solved.
+Idea: update embedding of the remaining nodes using encoder after agent arrives back to depot.
+**Implementation**:
+- Force RL agent to wait for others once it arrives to .
+- When every agent is in depot, apply encoder with mask to the whole batch.
 
 
+If you want to train your own model with AM-D approach:
+1. Prepare data (depo location Lat/Long, nodes location Lat/Long and capacity of the vehicles)
+2. Transform data with TensorFlow tranform_to_tensor [Here is Gist](https://gist.github.com/PiotrKrosniak/f488eea5b31a2d61e21554041a1ee59b) example with transforming from Pandas Data Frame
+3. Train the model using
