Bases: deephyper.search._search.Search

Methods

search

Execute the search algorithm.

terminate

Terminate the search.

search(max_evals: int = - 1, timeout: Optional[int] = None)

Execute the search algorithm.

Parameters
  • max_evals (int, optional) – The maximum number of evaluations of the run function to perform before stopping the search. Defaults to -1, will run indefinitely.

  • timeout (int, optional) – The time budget (in seconds) of the search before stopping. Defaults to None, will not impose a time budget.

Returns

a pandas DataFrame containing the evaluations performed.
