DoubleLinearExpr

DoubleLinearExpr

Return type: explicit

Arguments: BoolVar var

Constructs a linear expression from a Boolean variable. It deals with logical negation correctly.

Arguments: IntVar var

Constructs a linear expression from an integer variable.

DoubleLinearExpr

Return type: explicit

Arguments: double constant

Constructs a constant linear expression.

IsConstant

Return type: const bool

Returns true if the expression has no variable.

Sum

Return type: static DoubleLinearExpr

Arguments: absl::Span<const IntVar> vars

Constructs the sum of a list of variables.
