Strategy

class poisson_approval.Strategy(profile=None, voting_rule=None)[source]

A strategy profile (abstract class).

Parameters:
  • profile (Profile, optional) – The “context” in which the strategy is used.
  • voting_rule (str) – The voting rule. Possible values are APPROVAL, PLURALITY and ANTI_PLURALITY. Default: the same voting rule as profile if a profile is specified, APPROVAL otherwise.
