Creates a tournament

Parameters:

  • name – Tournament name

  • config_generator – Used to generate unique configs that will be used to evaluate competitors

  • config_assigner – Used to generate assignments of competitors to the configs created by the config_generator

  • world_generator – A functions to generate worlds for the tournament that follows the assignments made by the config_assigner

  • score_calculator – A function for calculating the score of all agents in a world After it finishes running. The second parameter is a dict describing any scoring context that may have been added by the world config generator or assigneer. The third parameter is a boolean specifying whether this is a dry_run. For dry runs, scores are not expected but names and types should exist in the returned WorldRunResults.

  • competitors – A list of class names for the competitors

  • competitor_params – A list of competitor parameters (used to initialize the competitors).

  • n_competitors_per_world –

    The number of competitors allowed in every world. It must be >= 1 and <= len(competitors) or None.

    • If None or len(competitors), then all competitors will exist in every world.

    • If 1, then each world will have one competitor

  • round_robin – Only effective if 1 < n_competitors_per_world < len(competitors). if True, all combinations will be tried otherwise n_competitors_per_world must divide len(competitors) and every competitor appears only in one set.

  • agent_names_reveal_type – If true then the type of an agent should be readable in its name (most likely at its beginning).

  • n_configs – The number of different world configs (up to competitor assignment) to be generated.

  • max_worlds_per_config – The maximum number of worlds to run per config. If None, then all possible assignments of competitors within each config will be tried (all permutations).

  • n_runs_per_world – Number of runs per world. All of these world runs will have identical competitor assignment and identical world configuration.

  • n_agents_per_competitor – The number of agents of each competing type to be instantiated in the world.

  • max_n_configs – [Depricated] The number of configs to use (it is replaced by separately setting n_config and max_worlds_per_config )

  • n_runs_per_config – [Depricated] The number of runs (simulation) for every config. It is replaced by n_runs_per_world

  • total_timeout – Total timeout for the complete process

  • base_tournament_path – Path at which to store all results. A new folder with the name of the tournament will be created at this path. A scores.csv file will keep the scores and logs folder will keep detailed logs

  • parallelism – Type of parallelism. Can be ‘serial’ for serial, ‘parallel’ for parallel and ‘distributed’ for distributed! For parallel, you can add the fraction of CPUs to use after a colon (e.g. parallel:0.5 to use half of the CPU in the machine). By defaults parallel uses all CPUs in the machine

  • scheduler_port – Port of the dask scheduler if parallelism is dask, dist, or distributed

  • scheduler_ip – IP Address of the dask scheduler if parallelism is dask, dist, or distributed

  • non_competitors – A list of agent types that will not be competing but will still exist in the world.

  • non_competitor_params – paramters of non competitor agents

  • dynamic_non_competitors – A list of non-competing agents that are assigned to the simulation dynamically during the creation of the final assignment instead when the configuration is created

  • dynamic_non_competitor_params – paramters of dynamic non competitor agents

  • exclude_competitors_from_reassignment – If true, copmetitors are not included in the reassignment even if they exist in dynamic_non_competitors

  • verbose – Verbosity

  • compact – If true, compact logs will be created and effort will be made to reduce the memory footprint

  • save_video_fraction – The fraction of simulations for which to save videos

  • forced_logs_fraction – The fraction of simulations for which to always save logs. Notice that this has no effect except if no logs were to be saved otherwise (i.e. no_logs is passed as True)

  • video_params – The parameters to pass to the video saving function

  • video_saver – The parameters to pass to the video saving function after the world

  • kwargs – Arguments to pass to the config_generator function

Returns:

The path at which tournament configs are stored
