Sensitivity analysis in geometric programming

A unified approach to computing first, second, or higher-order derivatives of any of the primal and dual variables or multipliers of a geometric programming problem, with respect to any of the problem parameters (term coefficients, exponents, and constraint right-hand sides) is presented. Conditions under which the sensitivity equations possess a unique solution are developed, and ranging results are also derived. The analysis for approximating second and higher-order sensitivity generalizes to any sufficiently smooth nonlinear program.
