favorite2However, when the strength of social interactions is significantly increased, a very high value of consensus among members is rapidly achieved [see Fig. 3(c)], the exploration of the landscape is slowed down, and the performance of the decision making-process significantly worsen, see Figure 2(c).
favorite5However, the random nature of the opinion dynamics still prevents full agreement from being achieved, see Fig. This, as observed in Figure 2(b), has a very beneficial effect as individuals continue exploring the fitness landscape looking for maxima, thus leading to higher performance of the collective decision-making pro-.
