In Example 6.17, we modified the design generated using MOLS so as to satisfy the operating system constraint. However, we did so by altering the values in specific entries so that all pairs are covered. Suggest other ways to resolving the infeasible values when using MOLS to generate test configurations. Discuss advantages and disadvantages of the ways you suggest.
