The following BWAPI release versions will be supported:
The only game type for the competition will be 1 vs. 1 full game StarCraft: BroodWar 1.16.1 with fog of war enabled.
Games will have a 'frame limit' of 86400 frames, to simulate one hour of gameplay. If a game goes this long, it will be stopped and the in-game score
will be used to determine the winner.
Make sure that each onframe call does not run longer than 42ms. Entries
that slow down games by repeatedly exceeding this time limit will lose games on time. In particular a bot will be given a game loss if one of the following occurs:
>= 1 frames exceed 10 seconds, or
>= 10 frames exceed 1 second, or
>= 320 frames exceed 55ms
The tournament will be round-robin, with as many rounds as possible.
All entries submission folders, including source code, will be published on the competition website once the competition has finished.
All games will be played at setLocalSpeed(0) (fastest setting). Please make sure that your bot
functions correctly on this setting. To avoid problems, base your 'timings' on unit counts or currentFrame() and not
machine time. The in-game lobby game speed slider will be set to Normal (i.e. latency frames = 3)
We reserve the right to reject entries if we feel the authors attempt
to obfuscate their code (like using silly or deceiving variable names
or encoding their algorithm in a 10MB FSM transition matrix stored on
disk). Authors who are concerned about the source code leaking
information that has not been published yet, are encouraged to submit
a technical report to their institutions that describes their entries
prior to submitting the code.
To simplify this process we ask authors to only use standard
development tools, that can be invoked via shell commands (such as
Visual C++). In case remote access is not feasible, we will need
detailed instructions for building each DLL.
Conflict of Interest
In order to avoid any conflict of interest or collusion between entries, only one entry per institution / author is allowed per competition.
Persistent File I/O
Bots will have read access to folder 'bwapi-data/read/' and write access to folder 'bwapi-data/write/', both of which will be in the standard location under the StarCraft root directory.
IMPORTANT: File I/O works as follows:
Again, due to the nature of overwriting the read folder with the contents of the write folder, your file names should be unique at least to the current opponent. Two popular choices for file naming schemes are:
- Before each game, the contents of the server-side read directory for your bot are copied to the client machine under 'bwapi-data/read/'. For the first round of the tournament this directory will be blank since a full round has not yet been played.
- During a game, you have write access to the 'bwapi-data/write/' folder and read access to the 'bwapi-data/read/' folder on the client you are currently playing on
- After the game ends, the contents of the 'bwapi-data/read/' folder are deleted, and the contents of the 'bwapi-data/write/' folder are sent to the server and stored in your bot's server-side write folder.
- WARNING: Step 3 may overwrite previous results if you are not careful in specifying unique filenames for each opponent that you play against.
- After each bot has played each other bot on the current map (one round robin on that map) the contents of each bot's server-side write folder are copied into the respective server-side read folder and the write folder is cleared.
- WARNING: Step 5 will over-write previous round data inside the server-side read folder. Your file output must either be cumulative, or have a filename scheme such that no overwrites will happen in order for your data to be preserved.
- The bot's server-side read folder is NEVER deleted throughout the tournament
- The next round starts, and from step 1 you will have access to your server-side read data from the previous rounds inside the client's 'bwapi-data/read/' folder
- Results_EnemyName.txt - Inside this file you store all data about your matches against bot EnemyName. This file will be overwritten every round on the server, so make sure to read its contents each game, and write out the cumulative results into the write folder so you do not lose data after a round
For example, you can store one line per map played inside this file so you have something like "EnemyName MapName Wins Losses ExtraData", then if you win a game on that map against that enemy, you read in the contents and then output "EnemyName MapName Wins+1 Losses ExtraData+NewData"
- Results_EnemyName_MapName_TimeStamp.txt - If you don't want to have a single file per enemy storing cumulative results, you can instead have a single file per game to store results with a unique time stamp or random number suffix. Please not that this is much slower, as your bot will play thousands of games and then have to process each file in the directory each time. Any time-out due to file processing is still a timeout and you will get a game loss. I strongly recommend the first option.
Any reading or writing of other directories is forbidden. You have a 1gb limit for all files in the read directory. If you go over this, it will be deleted.
No entry fee
Maybe some prizes
All replay files and source code will be made publicly available after the contest
StarCraft Brood War version 1.16.1 will be used for all games
Entries must use the version of the Brood War API provided on this site
Bots that perform malicious behavior will be disqualified and banned from all future contests. This includes but is not limited to:

Bots must disable the perfect information flag in the full-game tournament
Games in which an agent crashes StarCraft will be counted as a loss
Bots will be run in a VM running Windows 7 SP1 or Windows 10.
