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. หลักสูตรเต็มขั้นตอนต่อไป
