Affine arithmetic

Affine arithmetic (AA) is a computer arithmetic which was made to improve the performance of interval arithmetic.
Background
Today, the interval arithmetic technology which was made by Sunaga and R. Moore is used in many areas including validated numerics. But unfortunately, interval arithmetic is useless when numerical computation is repeated many times. Therefore, many experts have studied how to overcome this weakness. Affine arithmetic is one result of this movement.
Applications
Affine arithmetic is available in some interval arithmetic libraries like INTLAB. It is also used in the following fields:
Electrical circuits
Mixed signal systems
Numerical methods for ordinary differential equations
Optimization
Power flow
Root-finding algorithms
Improvements
Some experts are trying to improve affine arithmetic. Their results are known as the extended affine arithmetic or modified affine arithmetic.
