13.10 Modeling Networks

Networks of interacting biological systems, such as genes and gene products, can be modeled and investigated using graph algorithms. Despite the similarity to the term "graphics," graph algorithms are a different entity based on the discrete mathematical field of graph theory. Algorithms on graphs and their many variants (such as Petri nets) can store and investigate the properties of biochemical pathways and intra- and intercellular signalling pathways, for example.
