By applying a linear programming approach for the solution of two person-zero sum games with mixed strategies, it is shown that a linear optimization problem with multiple objective functions can be ...

In this note we construct some counterexamples concerning upper semicontinuity and linear upper and lower semicontinuity of the solution sets and ε -solution sets of nonlinear programming programs: ...

Diet models based on goal programming (GP) are valuable tools in designing diets that comply with nutritional, palatability and cost constraints.
