A NOVEL THREE-STAGE MULTI-POPULATION EVOLUTIONARY ALGORITHM FOR CONSTRAINED MULTI-OBJECTIVE OPTIMIZATION PROBLEMS

A novel three-stage multi-population evolutionary algorithm for constrained multi-objective optimization problems

Abstract Lots of real-world optimization problems are inherently constrained multi-objective optimization problems (CMOPs), but the existing constrained multi-objective optimization evolutionary algorithms (CMOEAs) often fail to balance convergence and diversity effectively.Therefore, a novel constrained multi-objective optimization evolutionary al

Among-population variation in microbial community structure in the floral nectar of the bee-pollinated forest herb Pulmonaria officinalis L.

BackgroundMicrobial communities in floral nectar have been shown to be characterized by low levels of species diversity, yet little is known about among-plant population variation in microbial community composition.Methodology/principal findingsWe investigated the microbial community structure (yeasts and bacteria) in floral nectar of ten fragmente
