The power and limits of modularity: A replication and reconciliation

Research Summary : We ask two questions: First, what are the underlying mechanisms that explain the power of modularity? Second, is the power of modularity robust in nonmodular problems? We replicate and then reconcile the key results in two prior models on modularity: E&L and S‐search. Our results yield several important insights. First, a significant portion of the advantage enjoyed by S‐search is attributed to multi‐bit mutation. Second,...
