gem install minigame
Usage:
To create new players:
employer = Player.new name: "IBM"
employee = Player.new name: "John Smith
To create a new list of strategies for all players in a game:
strategies = Strategy.new [{name: "Accept Training"},
{name: "Generic Training"},
{name: "Task Specific Training"},
{name: "Deny Training"}]
To create new StrategyProfiles:
# Regular training game -- generic strictly dominated
#
# Employer: | Task Specific | Generic
# Employee: ---------------|---------------------|------------------
# | |
# Deny Training | (-2, 0) | (-2, -1)
# ------------------------|---------------------|------------------
# Accept Training | (1, 4) | (5, -2)
# ------------------------|---------------------|------------------
strategy_profile = StrategyProfile.new
strategy_profile << {id: 1, strategy: generic, payoff: -2, player: employer}
strategy_profile << {id: 1, strategy: accept, payoff: 5, player: employee}
strategy_profile << {id: 2, strategy: generic, payoff: -1, player: employer}
strategy_profile << {id: 2, strategy: deny, payoff: -2, player: employee}
strategy_profile << {id: 3, strategy: task, payoff: 0, player: employer}
strategy_profile << {id: 3, strategy: deny, payoff: -2, player: employee}
strategy_profile << {id: 4, strategy: task, payoff: 4, player: employer}
strategy_profile << {id: 4, strategy: accept, payoff: 1, player: employee}
To create a new game:
gs = Game.new
gs.strategy_profiles = strategy_profile
To get the list of strictly dominated strategies:
gs.strictly_dominated_list
[{:name=>"Generic Training"}, {:name=>"Deny Training"}]
To get the list a weakly dominated strategies:
# training game -- generic weakly dominated (not realistic)
#
# Employer: | Task Specific | Generic
# Employer: ----------------|---------------------|------------------
# | |
# Deny Training | (-2, -1) | (-2, -1)
# ------------------------|---------------------|------------------
# Accept Training | (1, 4) | (5, -2)
# ------------------------|---------------------|------------------
gs.weakly_dominated_list
[{:name=>"Generic Training"}]
To get the list strategy profiles that are nash equilibria:
gs.nash
[["Accept Training", "Task Specific Training"]]
