Introductory Example: Linear Programming Models: Interior Point algorithm Consider the Linear Programming problem in the "An Introductory Example" section in the chapter on the LP procedure.

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: ...

Five integer linear programming models are posed, each based on a different optimality criterion dealing with manpower smoothing. By means of two hypothetical examples the models are tested for their ...
