Numerical and Computational Methods

Branches that design and analyse methods for obtaining numerical answers to mathematical problems on a computer. An entry belongs here when its cited source describes approximation algorithms, the control of rounding and discretisation error, the solution of equations and linear systems by iteration, or the broad field of applied and computational mathematics that these methods serve. It does not belong here when the branch is about choosing the best of many options or steering a dynamical system, which are covered by the optimization and control group. The group covers the practical side of calculation that links pure analysis to science and engineering.
