Answer 2

Answer:

The two-phase technique is algebraically simpler than the  M method.

Step-by-step explanation:

The two-phase technique is algebraically simpler than the huge M method.

The "common sense approach" is the Big-M way of dealing with cases containing bogus variables. Essentially, the idea is to make the false variables, via their coefficients in the objective function, so expensive or unprofitable that any possible solution to the genuine problem would be favoured, provided the original instance had no feasible solutions at all.

Two-Phase Method This approach varies from the Simplex method in that it requires the completion of an auxiliary problem that must minimise the sum of fake variables. After resolving the first issue and restructuring the final board, we proceed to the second phase, which consists of creating a standard Simplex.
