“…The figures 3(d, e, f) and 3(j, k, l) present top 10% of figures 3(a, b, c) and 3(g, h, i), respectively. For von Neumann neighbourhood and medium (L = 10) and larger organisations we observe minimum of n(K) curves for p ≈ 0.6 [13]. This counter-intuitive effect is directly associated with restriction (1b)-for high enough initial concentration of chunks of knowledge p some agents acquire high level of competences quite quickly and do not want share their knowledge with their not-so-smart neighbours.…”
