ColgenInstance:(?X =:= ?Y)
Constrains X to be equal to Y.
- X
- Partial linear expression
- Y
- Partial linear expression
Description
	Logically: Constrains X to be equal to Y. X and Y are partial
	linear expressions. Partial linear expressions may contain
	terms of the form implicit_sum(+Var) in addition to
	any terms allowed within a standard linear
	expression. Variables occurring inside implicit_sum/1
	terms are taken to be subproblem variables whose instantiation
	will correspond to the coefficient of a generated master
	problem variable in this constraint. Operationally, the
	constraint gets delayed until the external solver state for
	ColgenInstance is invoked.
