Graphs and NetworksApplications There are countless other graphs in science, engineering or everyday life: The links between atoms in molecules and crystal grids form a graph. The spread of diseases and epidemics can be modelled using a network. In Biology, the evolutionary trees that show the ancestry of species form a graph. The different components of electric circuits and computer chips form a network. The grammatical structure of languages can be modelled using graphs, for example to create translation algorithms. Graphs also have many applications in probability, game theory and financial mathematics. Full CourseNext Step
