Parametric linear programming

Parametric linear programming is the study of how optimal properties depend on data parametrizations the study is nearly as old as the eld of linear programming itself, and it is important since it highlights how a problem.

Parametric programming more generally • reduced costs depend linearly on θ • bfs and basis matrix b, optimal for θ 1 ≤ θ ≤ θ 2 • reduced cost of x j negative for θθ 2 – reduced cost is zero for θ = θ 2 • if b−1a j ≤ 0, g(θ)=−∞ for θθ 2 • otherwise, bring x j into basis • still have optimal solution at θ = θ 2.

Parametric optimization is a relatively mature field with many contributions, see, eg, [5,6,7] for reviews with the exception of a few algorithms for linear or purely integer programs the available literature assumes that parameters only influence the objective function and/or the right-hand side of the constraints. Parametric programming parametric programming is a type of mathematical optimization, where the optimization problem is solved as a function of one or multiple parameters developed in parallel to sensitivity analysis, its earliest mention can be found in a thesis from 1952.
