WebA consumer-resource system is considered, where the consumer moves between multiple source-sink patches with both resource and toxicant. By applying Lyapunov method and theoretic-graph theory, we show global stability of positive equilibria in the system. Then it is shown that diffusion could make the consumer persist in sinks, even make it ... WebFeb 20, 2024 · Video. Determine whether a universal sink exists in a directed graph. A universal sink is a vertex which has no edge emanating from it, and all other vertices have an edge towards the sink.

WebThe max-flow min-cut theorem is a network flow theorem. This theorem states that the maximum flow through any network from a given source to a given sink is exactly the sum of the edge weights that, if removed, would totally disconnect the source from the sink. In other words, for any network graph and a selected source and sink node, the max ... WebJan 20, 2024 · Graph databases require a change in the mindset from computational data to relationships.
