Reconsidering Fitness and Convergence in Co-evolutionary Design MARY LOU MAHER AND PETER

چکیده
Computational evolution provides a mechanism for searching a space of potential solutions according to a specified fitness function. In design, the search for potential solutions is often interleaved with changes in the requirements for the solution. We propose a model of design that uses a co-evolutionary computational process. Specifically, we present design as a parallel search for both design requirements and design solutions. Further, we develop a coevolutionary process in which the interaction between requirements and solution redefine the current fitness function. The concepts of fitness and convergence in computational evolution do not necessarily have the same meanings in a co-evolutionary process in which the fitness function changes. An additional consideration not present in computational evolution is the interaction between the parallel search spaces. We present a mechanism for interaction which results in a kind of co-evolution called mutualism.

متن کاملReconsidering the Sedentary Behaviour Paradigm
AIMS Recent literature has posed sedentary behaviour as an independent entity to physical inactivity. This study investigated whether associations between sedentary behaviour and cardio-metabolic biomarkers remain when analyses are adjusted for total physical activity. METHODS Cross-sectional analyses were undertaken on 4,618 adults from the 2003/04 and 2005/06 U.S. National Health and Nutrit...
متن کاملNew Strategies for Treating Myomas
Laparoscopic minilaparotomy in 6 patients using the Maher abdominal elevator facilitated both quicker enucleation and morcellation of the myoma and suture of the myoma cavity. Myoma reduction in 12 patients by electrosurgery resulted in a 60% reduction in myoma diameter with failure in 2 patients. This technique may avoid myomectomy and be particularly useful in patients with infertility or nea...
