【摘要】The predator/prey (capture) problem is a prototype of many network-related applications.We study the capture process on complex networks by considering multiple predators from multiple sources.In our model,some lions start from multiple sources simultaneously to capture the lamb by biased random walks,which are controlled with a free parameter α.We derive the distribution of the lamb's lifetime and the expected lifetime
