Gradient network
open-in-new
<p>In <a href="/facts/Network_science/Ul7FMUg3">network science</a>, a gradient network is a directed <a href="/facts/Subnetwork/s1rQsNDv">subnetwork</a> of an undirected "substrate" <a href="/facts/Computer_network/3w5RM99p">network</a> where each <a href="/facts/Node_(networking)/LBp2vNcJ">node</a> has an associated <a href="/facts/Scalar_potential/lXKtCr1c">scalar potential</a> and one out-link that points to the node with the smallest (or largest) potential in its neighborhood, defined as the union of itself and its <a href="/facts/Neighbourhood_(graph_theory)/E6V1hk6b">neighbors</a> on the substrate network. </p>
