ZZZKBot is a StarCraft AI, written by Chris Coxe. It uses BWAPI as an API for interacting with Starcraft: Broodwar.

Based On

ZZZKBot was written from scratch (was not based on any other bots).

Starcraft/BWAPI-related 3rd-party Libraries Used

Doesn't use any 3rd-party bots/frameworks/wrappers/libraries/modules apart from BWAPI.

AI Techniques

• A multi armed bandit online learning algorithm for opening selection.
• A simple greedy distance-based distribution of workers to mineral patches.

Facts

• It is designed to compete against other bots. It is not designed to compete against humans.
• It competes in AIIDE and CIG bot-vs-bot competitions.
• It is a later version of ZZZBot after it was renamed from ZZZBot to ZZZKBot in October 2015.

Strategies

• 4pool. Default build.
• Speedling build.
• Hydra rush.
• 1 base mutalisk play.

The 4pool, speedling and hydra rush builds normally transition into 1 base muta (otherwise 1 base guardian).

From AIIDE2017 onwards, ZZZKBot uses the results from past games for an opponent to decide which strategy to try the next game against that opponent.
