SINGLE-MATERIAL WORLDS

We will start by defining the schematic environment for TOAST. The environment has exactly one material to be cooked and one of each tool needed to cook it. To simplify further, we will start by ignoring even the tools. Then we will

1. Solve the no-tools case.
2. Reduce the self-resetting tools case to the no-tools case.
3. Reduce the general case to the self-resetting tools case.

• SINGLE-MATERIAL WORLDS WITH NO TOOLS
• SINGLE-MATERIAL WORLDS WITH SINGLE-STATE TOOLS
• SINGLE-MATERIAL WORLDS WITH GENERAL TOOLS
