文摘

Novel kinetic models for the influence of the competence in the evolution of decisions in multi-agent systems. The evolution of the competence depends on a social background in which individuals grow and on the possibility to learn from the more competent ones. The hypothesis of equality bias induces the agents to behave in the same way as if they were as good, or as bad, as their partner, leading to suboptimal collective decisions. Numerical experiments based on Monte Carlo techniques for the Boltzmann equation in the quasi-invariant scaling.
