?X $=< ?Y

EplexInstance:(?X $=< ?Y)

Constrains X to be less than or equal to Y.
X
Linear expression
Y
Linear expression

Description

Logically: Constrains X to be less than or equal to Y. X and Y are linear expressions. Operationally, the constraint gets delayed until the external solver state for EplexInstance is invoked.

The $ version of the arithmetic constraints are provided to allow code to be written which does not specify the solver. They are equivalent to their eplex instance counterparts without the $ prefix.
