The interaction diversity, fitness improvement, final fitness, and k-topologies are associated in a non-trivial manner. (a) Some benchmark functions appear to consistently present higher interaction diversity when compared to other regardless of the underlying communication topology. In the results for F6 function, (b) although the correlation of −0.79 indicates a strong negative linear relationship between the average interaction diversity and the mean fitness improvement, one can easily see that they are associated in a non-monotonic way. (c) Similarly, the final quality of the fitness found by the swarm also presents a non-monotonic behavior regarding k-regular topologies and consequently, interaction diversity
