Battle¶
This module defines the Battle
class and thus what each battle type can do to customize how it runs and
scores the programs. If you are implementing your own custom battle types, make sure they adhere to the api
specifications laid out here.
algobattle.battle.Battle
¶
Bases: BaseModel
Base for classes that execute a specific kind of battle.
Each battle type determines what parameters each fight will be fought with, how many fights are fought, and how they will ultimately be scored.

UiData
¶
Bases: BaseModel
Object containing custom diplay data.
The display data object will be displayed as key-value pairs generated from the :meth:.field
method.
You can use the normally available pydantic config options to customize what these will look like.

score(config)
abstractmethod
¶
Calculates the score the solver has achieved during this battle.
Should always be a nonnegative float, with higher values indicating a better performance of the solver.

name()
classmethod
¶

run(max_size, *, with_results=False, **kwargs)
async
¶
Execute a single fight of a battle.
First the generator will be run and its output parsed. Then the solver will be given the created instance and run. Its output gets parsed into a solution, which will then be scored. The timeout, space, and cpu arguments each override the corresponding match config options if set. Leaving them unset results in the config options being used.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
max_size |
int
|
The maximum instance size the generator is allowed to create. |
required |
timeout_generator |
Timeout in seconds for the generator to finish running. |
required | |
space_generator |
Memory space in MB the generator has access to. |
required | |
cpus_generator |
Number of physical cpu cores the generator can use. |
required | |
timeout_solver |
Timeout in seconds for the solver to finish running. |
required | |
space_solver |
Memory space in MB the solver has access to. |
required | |
cpus_solver |
Number of physical cpu cores the solver can use. |
required | |
generator_battle_input |
Additional data the generator will be provided with. |
required | |
solver_battle_input |
Additional data the solver will be provided with. |
required | |
generator_battle_output |
Class used to parse additional data the generator outputs into a python object. |
required | |
solver_battle_output |
Class used to parse additional data the solver outputs into a python object. |
required | |
with_results |
bool
|
Whether to return the raw result objects. |
False
|
Returns:
Type | Description |
---|---|
Fight | tuple[Fight, GeneratorResult, SolverResult | None]
|
The resulting info about the executed fight, and the results if the flag has been set. |
