The ratio

(cost of optimal solution to original problem)/(cost of optimal solution to relaxed problem)

is called the integrality gap of an IntegerLinearProgram.?

In case of a maximization problem, the integrality gap is the reciprocal. The integrality gap of the problem is the worst-case integrality gap for any instance of the problem.
