  7. 7. Game Informational Evaluation [Shannon]
  8. 8. Informational Impedance Adaptation [Moles (1988)] Apprenticeship process = Adaptative function which asymptote reveals perfect fitting between transmitter and receiver directories. Cost of communicative transactions between speakers and listeners = Transmitter-receiver directories fitting quantification Entropy calculation
  9. 9. Order Spectrum Entropy 1 H ( X ) = I ( X ) = − ∑ p ( x) log p ( x) = ∑ p ( x) log . x∈ X x∈ X p( x) Information Dimension Correlation Dimension log ∑ p ²( x) 1 Dc = lim x∈ X ∑ p( x) log x∈ X p( x) log k DS = log k [Moles (1988)]
