Detailed Description

Auxiliay structure to store the domain of a variable.

Stores information about the sign that a decision variable can have:

• Variables with non_negative set to true are supposed to be parameterized as \(x=u\), \(u\geq 0\).
• Variables with non_positive set to true are supposed to be parameterized as \(x=-v\), \(v\geq0\).
• Variables with both non_positive and non_negative set to false are supposed to be parameterized as \(x=u-v\), \(u\geq0\) and \(v\geq0\).
• Variables with both non_positive and non_negative set to true are "degenerate".

This structure is not meant to be used directly by the user.
