2. A Hero’s Journey...

5. The Monomyth
Conflict
Journey
Hero
Mentor
Threshold Guardians
Herald
Shapeshifter
Shadow
Ally
Trickster

6. Motivation
Is it possible to create a multi-paradigm
three-layered system
EC
LR
ABM
that is able to generate massive
backstories following the monomyth
guidelines?

7. Our previous work (Evostar 2015)
ABM: FSM that models rats moving in a grid
Weakness:
a) Fixed parameters for world size and duration
b) Limited number of actions of the rats
c) Fitness: Arbitrary count of events in logs

8. The new approach
A new system architecture: A Java8 multi-paradigm Java/Prolog application
build over SOLID principles, TDD and Clean code.
A new ABM: ColorForms, a simple game where different pieces (squares,
triangles and circles) interact in a board in order to change their colours. On top of
this, we build a world where each piece has affinities, goals, strategies and
emotions.
A new method to measure the fitness: Logical reasoning modeled in a
declarative language (PROLOG) over events of the world. The logical theory is
extracted from the interpretations of the archetypes described by Vogler in The
Writer’s Journey.

9. System Architecture

10. ABM: ColorForms
World
Agents
Objects
Events

11. Behaviour of the agent

12. Events for the board configuration

13. Daily pieces’ events

14. Conditions in the Behaviour Tree (emotions/checks)

15. Actions in the Behaviour Tree (Strategies)

16. LR:

17. EC:
Individual: 52 parameters describing:
size of the world
number of pieces
number of virtual days
weights for joy (shape, background,
foreground, neighbor)
probability of fear, surprise, sadness

18. Three Fitness compared
Amount of Monomyth Occurrences
Found (M)
Amount of All Occurrences Found (A)
Amount of All Occurrences Distributed
by Predicates (AD)
(15 runs by individual)

19. Results

20. Conclusions
Emotion-driven agents in a virtual world (ColorForms)
Events generated as logical predicates evaluated to deduce the monomyth
Best fitness: search the appearance (and diversity) of facilitators
Future: human-guided, text generation, complex behaviour
