Building Blocks as Experiences in Dynamic Capacitated Arc Routing Problems
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT The dynamic capacitated arc routing problem (DCARP) aims to update the service paths of vehicles in the capacitated arc routing problem when uncertain factors deteriorate the current schedule of vehicles' services. A DCARP scenario comprises a series of DCARP instances that share similarities with each other. Therefore, optimisation experience

Effects of temperature and browning on the functional response of a freshwater top predator
Journal of Animal Ecology, EarlyView.This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.
