Chapman & Hall medical microbiology seriesgraphs when he was asked to consider the problem of the Königsberg bridges (in the 1730s). Problems in (finite) graph theory are often enumeration problems, and thus can become rather intricate to be solved. However, in the late 1950s and early 1960s the Hungarian mathematicians Paul Erdös and Alfre

Though usually, in taxonomy, clusters are nothing more than the result of an algorithm, graph theory makes it possible to define clusters properly in mathematical terms. One convenient definition — as shown in Subsections 3.1.2 and 3.2.

Classifications by Multigraphs: Three Examples from Medicine,sters mathematically, graph theory provides the scientist with tools to formulate and test null hypotheses on the structures of data sets. Thus, cluster analysis is raised from a tool of exploratory statistics to a helpful method of inference statistics.
