Detailed Description

PresburgerSpace is the space of all possible values of a tuple of integer valued variables/variables.

Each variable has one of the three types:

Dimension: Ordinary variables over which the space is represented.

Symbol: Symbol variables correspond to fixed but unknown values. Mathematically, a space with symbolic variables is like a family of spaces indexed by the symbolic variables.

Local: Local variables correspond to existentially quantified variables. For example, consider the space: (x, exists q) where x is a dimension variable and q is a local variable. Let us put the constraints: 1 <= x <= 7, x = 2q on this space to get the set: (x) : (exists q : q <= x <= 7, x = 2q). An assignment to symbolic and dimension variables is valid if there exists some assignment to the local variable q satisfying these constraints. For this example, the set is equivalent to {2, 4, 6}. Mathematically, existential quantification can be thought of as the result of projection. In this example, q is existentially quantified. This can be thought of as the result of projecting out q from the previous example, i.e. we obtained {2, 4, 6} by projecting out the second dimension from {(2, 1), (4, 2), (6, 2)}.

Dimension variables are further divided into Domain and Range variables to support building relations.

Variables are stored in the following order: [Domain, Range, Symbols, Locals]

A space with no distinction between types of dimension variables can be implemented as a space with zero domain. VarKind::SetDim should be used to refer to dimensions in such spaces.

Compatibility of two spaces implies that number of variables of each kind other than Locals are equal. Equality of two spaces implies that number of variables of each kind are equal.

PresburgerSpace optionally also supports attaching an Identifier with each non-local variable in the space. This is disabled by default. resetIds is used to enable/reset these identifiers. The user can identify each variable in the space as corresponding to some Identifier. Some example use cases are described in the Identifier documentation above. The type attached to the Identifier can be different for different variables in the space.
