Epsilon-inflation is an efficient tool for verifying and enclosing solutions of mathematical problems of various kinds. It consists in widening an interval quantity $$[x]$$ to a new one $$[x]_\varepsilon$$ such that $$[x]_\varepsilon$$ contains $$[x]$$ in its interior. The amount of widening is steered by a parameter usually called $$\varepsilon$$ which gave the technique the name. It is used to verify the selfmapping property of some given function.
