In the field of cultural evolution, cognitive agents are either seen as perfect imitators who reproduce cultural variants veridically (e.g. Boyd & Richerson 1985) or as imperfect imitators who transform the variants as they replicate them (e.g. Sperber 1996). In this poster, I explain how the transformative view of cognition applies to not only to the generation of variants, but also to the way...

Seeker optimization algorithm (SOA) is a novel search algorithm based on simulating the act of human searching, which has been shown to be a promising candidate among search algorithms for unconstrained function optimization. In this article we propose a modified seeker optimization algorithm. In order to enhance the performance of SOA, our proposed approach uses two search equations for produc...

x0. Introduction. Consider a game played by 2 players, whom we call the hider and the seeker. Let S be a simplex of dimension n, with vertices x 0 , x 1 ; : : :; x n , and M a subcomplex of S, known to both the hider and the seeker. Let be a simplex of S, known only to the hider. The seeker is permitted to ask questions of the sort \Is vertex x i in ?" The seeker's goal is to determine whether ...

There are several obstetric, medical, and surgical disorders that share many of the clinical and laboratory findings of patients with severe preeclampsia-hemolysis, elevated liver enzymes, and low platelets syndrome. Imitators of severe preeclampsia-hemolysis, elevated liver enzymes, and low platelets syndrome are life-threatening emergencies that can develop during pregnancy or in the postpart...

Exercise-induced bronchoconstriction (EIB) is described by transient narrowing of the airways after exercise. It occurs in approximately 10% of the general population, while athletes may show a higher prevalence, especially in cold weather and ice rink athletes. Diagnosis of EIB is often made on the basis of self-reported symptoms without objective lung function tests, however, the presence of ...

In an innovation contest, a rm (the seeker) facing an innovation related problem (e.g. a technical R&D problem) posts this problem to a population of independent agents (the solvers) and then provides an award to the agent that generated the best solution. In this paper, we analyze the interaction between a seeker and a set of solvers. Prior research in Economics suggests that having many solv...
