The feasible regions of linear programming are defined by a set of inequalities. In mathematics, an inequality is a relation that holds between two values when they are different (see also: equality). 1  The notation a â  b means that a is not equal to b.
Inequality, by contrast, is always a relative term: it refers to the difference between levels of living standards, income etc. across the whole economic distribution. In practice, poverty and inequality often rise and fall together but this need not necessarily be the case.
