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)
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, ...
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

40. Validation & Calibration
41. # validation # == # functional test
44. # Calibration # f(x, y, z, ?) = a
45. Simulate & Prepare yourself
46. Live Demo
