Fitness model (2001):
Attachment prob ∝ η_i · k_i (fitness × degree).
With
uniform fitness
: power-law P(k)~k^(-γ), γ≈3, similar to BA.
With
high-temperature
fitness:
Bose-Einstein condensation
— a single "winner" node accumulates finite fraction of all links (the network's "Google").
Node color = fitness; size = log(degree).
