32   	 * This separator generates a collection of cuts constructed by the reformulation-linearization technique (RLT).
33   	 * For an LP row L and a variable x in [lb,ub], L is multiplied either with (ub-x) or with (x-lb). All known terms that
34   	 * appear in the product are replaced by their respective auxiliary variable and all unknown terms are replaced by a
35   	 * suitable linear relaxation, e.g., McCormick. In general, the separator computes four different cuts for a row with
36   	 * finite sides and a variable with finite bounds.
