1. The most effective and widely used procedure for solving ILP problems is called:

a. LP relaxation.

b. The cutting plane approach.

c. The branch-and-bound (B&B) algorithm.

d. Simplex.

2. Many ILP packages allow you to specify a suboptimality tolerance of X% (where X is some numeric value). This number is used to:

a. Simplify complex computations.

b. Increase the number of evaluated alternatives.

c. Tell the B&B algorithm to stop to prevent evaluation of thousands of candidate problems.

d. Remove infeasible alternatives from consideration.

3. By default, Solver uses a suboptimality tolerance factor of 5%. This means that:

a. No integer solution can be found.

b. Integer solution was found within the stated tolerance.

c. Additional computations are required to find the optimal solution.

d. A B&B procedure is not effective in finding a solution to the problem.

4. The first step in formulating ILP problems is:

a. Defining the decision variables.

b. Implementing the model in a spreadsheet.

c. Defining the objective function.

d. Defining the constraints
