Complex Syst. 10, Suppl. 1, 85-110 (2007).} \itemab Summary: We investigate the performances of collective task-solving capabilities and the robustness of complex networks of automata using the density and synchronization problems as typical cases. We show by computer simulations that evolved Watts--Strogatz small-world networks have superior performance with respect to several kinds of scale-free graphs. In addition, we show that Watts--Strogatz networks are as robust in the face of random perturbations, both transient and permanent, as configuration scale-free networks, while being widely superior to Barab\'asi--Albert networks. This result differs from information diffusion on scale-free networks, where random faults are highly tolerated by similar topologies. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1142/S0219525907001124} \end
