Changing the bot

• Bot behavior is controlled by src/brainfuck/bot.bf
• The inputs that the bot gets is controlled by the Python code in the inputs option in src/agent.cfg

Brainfuck implementation details

This bot uses a relatively standard implementation of brainfuck. Here are the details:

• There is a 30,000 cell tape, where each cell is initialised to zero
• Each cell has a value range of an 8-bit char (-128 to 127)
• Cell overflow/underflow wraps the cell to the opposite end of the cell range
• Moving the pointer to the left (<) of cell 0 limits the pointer to cell 0
• Moving the pointer to the right (>) of cell 29,999 limits the pointer to cell 29,999
• The # symbol can be used for debug printing

Troubleshooting

Printing debug values

You can place the pound/hash symbol (#) in your brainfuck code to print the current cell, its value, and the value for the following for 19 cells.

%1 is not a valid Win32 application

If you get this error, src/python/interpreter.dll hasn't been compiled with the same architecture as your Python environment. To fix this, compile the interpreter project (project provided in CMakeLists.txt) with the right architecture.
