dc.description.abstract | We present a log-barrier based algorithm for linearly constrained convex differentiable programming problems in nonnegative variables, but where the objective function may not be differentiable at points having a zero coordinate. We use an approximate centering condition as a basis for decreasing the positive parameter of the log-barrier term and show that the total number of iterations to achieve an ε-tolerance optimal solution is O(|log(ε)|)×(number of inner-loop iterations). When applied to the n-variable dual geometric programming problem, this bound becomes O(n2U/ε), where U is an upper bound on the maximum magnitude of the iterates generated during the computation. © 1995 Plenum Publishing Corporation. | |
