In mathematics, approximation theory is concerned with how functions can be approximated with other, simpler, functions, and with characterising in a quantitative way the errors introduced thereby.

ApproximationAn approximation is the intelligent guess based on the available information and on the degree of accuracy required. These values are nearly correct, but not exact. Science The scientific method is carried out with a constant interaction between scientifi	Approximation algorithmIn computer science, approximation algorithms are an approach to attacking NP-hard optimization problems. Since it is unlikely that there can ever be efficient exact algorithms solving NP-hard problems, one settles for non-optimal solutions, but requires	Approximation propertyOperator theory In mathematics, a Banach space is said to have the approximation property AP in short), if every compact operator is a limit of finite rank operators. The converse is always true. Every Hilbert space has this property; for a general Banach
Approximation errorIn the mathematical subfield of numerical analysis the approximation error in some data is the difference between the exact value and the value used. An approximation error can occur because #the measurement of the data is not precise (due to the instrume	Approximation theoryIn mathematics, approximation theory is concerned with how functions can be approximated with other, simpler, functions, and with characterising in a quantitative way the errors introduced thereby.
