    In this article we present an Elitism Levels Traverse Mechanism that we designed to find bounds on population-based Evolutionary algorithms solving unimodal functions. We prove its efficiency theoretically and test it on OneMax function deriving bounds c{\mu}n log n - O({\mu} n). This analysis can be generalized to any similar algorithm using variants of tournament selection and genetic operators that flip or swap only 1 bit in each string.Comment: accepted to Congress on Evolutionary Computation (WCCI/CEC) 201

    Investing in Knowledge: On the Trade-Off between R&D, ICT, Skills and Migration

    This paper deals with the complementarity between skills and knowledge by investigating particularly tacit knowledge flows between countries and regions. The main findings are threefold. First, there seems to exist a trade-off between acquiring knowledge through performing and putting effort in R&D and through investing into access to the public knowledge basin. Secondly, migration of high-skilled labour from South to North appears, as a result of the introduction and rapid evolution of ICT, no longer a dominant trend. Finally, the observed trade-off goes hand in hand with the accumulation and formation of tacit knowledge.research and development ;
