With the above ideas, we focus on the simplex method and study how it efficiently solves a linear program. Finally, we discuss some properties of unbounded and infeasible problems, which can help us identify whether a problem has optimal solution.
Webb17 juli 2024 · Solution We choose the variables as follows: Let x = The number of hours per week John is employed. and y = The number of hours per week Mary is employed. The objective function is C = 15 x + 25 y The fact that each must work at least one hour each week results in the following two constraints: x ≥ 1 y ≥ 1

The question is, is there a way to sniff out possible unboundedness before even starting the simplex algorithm? For example,
