Problem: Given a semantic network, determine which concepts are the earliest to be fully activated (activation above a given threshold) in response to multiple simultaneous input stimuli (concept activations).
Background: A simple model of cognition considers all known concepts
connected in a network, known as a semantic network. A concept is directly
connected by links to its most-closely-related concepts. When a concept receives
an activation signal from one of its neighbors, it in turn passes along the
activation signal to each of its other neighbors. This is referred to as spreading
activation. Activation from one node to another takes a single unit of time.
An activation threshold T refers to the number of activation signals that must
be received by a node for that node to be considered "fully activated".
