The Snakes

Snake With No brain

This snake performs very basic analysis on each turn to avoid taking actions that will lead to certain death. This analysis consists of three steps:

1. Avoid hitting it's own neck
2. Avoid hitting walls
3. Avoid hitting any snake's body

Once these actions have been removed, the snake then picks randomly from the remaining actions.

usage: main.py [-h] [-c COLOR] [-p PORT] [-d] [-s] [--stats_file STATS_FILE] [--print_level {1,2,3}]

optional arguments:
  -h, --help            show this help message and exit
  -c COLOR, --color COLOR
                        Hex color code. Default random.
  -p PORT, --port PORT  Port to run Battlesnake on. Default 8001.
  -d, --deployed        Opens server to the internet
  -s, --save_games      Save game data to file for training
  --stats_file STATS_FILE
                        Path to store game stats
  --print_level {1,2,3}
                        1: silence all prints 2: (Default) silence move(), info(), start() 3: print from all endpoints

Snake With A Brain

This snake performs the exact same analysis as Snake With No Brain. However, instead of chosing randomly from the non-certain-death moves, it uses a nueral network to rank the remaining actions and picks the best one.

usage: sl_snake.py [-h] [-c COLOR] [-p PORT] [-d] [-s] [-m MODEL] [--stats_file STATS_FILE] [--print_level {1,2,3}]

optional arguments:
  -h, --help            show this help message and exit
  -c COLOR, --color COLOR
                        Hex color code. Default random.
  -p PORT, --port PORT  Port to run Battlesnake on. Default 8001.
  -d, --deployed        Opens server to the internet
  -s, --save_games      Save game data to file for training
  -m MODEL, --model MODEL
                        Filename of model to use for predictions. Default basicModel.h5
  --stats_file STATS_FILE
                        Path to store game stats
  --print_level {1,2,3}
                        1: silence all prints 2: (Default) silence move(), info(), start() 3: print from all endpoints
