 Rather than the usual approach to determine the area (using small clay tokens to lay out a rectangle representing the field, and counting them one by one to determine the area) Ikram has an insight. He realizes he has seen these numbers before and he knows the answer. Last week he had 8 seperate orders of 15 bottles of wine, this totalled 120 bottles.
 Later that week, while travelling (with idle time to think) he realisees he could list all the possible areas of a field with a length of 1 to 10, and a width of 1 to 10.

 Ikram is frustrated because his large trading operation requires keeping track of many different sized quantities. He uses different symbols for 1s, 10s, 60s, and 600s, but it's becoming unwieldy. One day, while watching his assistants arrange storage jars (which are stacked in neat rows and columns), he notices how the position of each jar tells him something about its contents. This gives him an idea: what if the position of a number symbol could tell you its value? He experiments with a system where a symbol's position indicates whether it represents ones, sixties, or three-thousand-six-hundreds.

+- the core logic of the game (implemented in rust)
+- the frontend (implemented in flask)
+- the RL agent (implemented in python / jax)
+
+## Core logic
+
+Why did I implement the core logic in rust?
+Good question. 
+
+I knew I wanted to do some reinforcement learning, so I wanted the core logic to be fast.
+I also wanted to learn rust.
+
+
+I have implemented the core game in rust with some small changes;

+- encryption is based on a 'simple' version of enimga. Aka, a 2 rotor polynumeric substitution cipher.
+- re-encryption now costs victory points
+- you can send as many or as few resources to a single battle as you like (rather than max 2).
