9. Agent Based Model

10. Map National Geographics, ©2011

11. map = Map.new(4, 4)

12. point = Point.new point_north = Point.new point.neighborhood[:north] = point_north point_north.neighborhood[:south]

    = point # ...

13. John DellAngelo, ©2013 Agent

14. agent = Agent.new(age, start_point, stm)

15. agent.perceive # => {}

16. agent.act # => :walk agent.walk(:east)

17. None

18. agent.age # => 1

19. agent.commit # => #<ZombieEpidemic::State:... # @name=:susceptible, ...

20. State

21. state = State.new(:susceptible) state.define_possible_actions( ->(agent) { [:walk, :stay, :fight].sample }

    )

22. state.decide_action_for(agent) # => :walk

23. infected = State.new(:susceptible) state.add_transition( infected, ->(state, agent) { true }

    )

24. state.trigger_transition(agent) # => #<ZombieEpidemic::State:... # @name=:infected, ...

25. None

26. State Transition Machine

27. stm = StateTransitionMachine.new # create states: # - susceptible #

    - infected # - zombie # - dead # create transitions # set default initial state

28. Simulation Loop

29. steps = 100 agents = create_the_agents steps.times do agents.each do

    |agent| agent.act; agent.age end agents.each { |agent| agent.commit } remove_the_deads(agents) end

30. steps = 100 agents = create_the_agents steps.times do agents.each do

    |agent| agent.act; agent.age end agents.each { |agent| agent.commit } remove_the_deads(agents) end

31. steps = 100 agents = create_the_agents steps.times do agents.each do

    |agent| agent.act; agent.age end agents.each { |agent| agent.commit } remove_the_deads(agents) end

32. steps = 100 agents = create_the_agents steps.times do agents.each do

    |agent| agent.act; agent.age end agents.each { |agent| agent.commit } remove_the_deads(agents) end

33. steps = 100 agents = create_the_agents steps.times do agents.each do

35. steps = 100 agents = create_the_agents steps.times do agents.each do

36. steps = 100 agents = create_the_agents steps.times do agents.each do

    |agent| agent.act; agent.age end agents.each { |agent| agent.commit } remove_the_deads(agents) end

37. steps = 100 agents = create_the_agents steps.times do agents.each do

    |agent| agent.act; agent.age end agents.each { |agent| agent.commit } remove_the_deads(agents) end
