Abstract
An interior-point algorithm whose initial point is not restricted to a feasible point is called an infeasible-interior-point algorithm. The algorithm directly solves a given linear programming problem without using any artificial problem. So the algorithm has a big advantage of implementation over a feasible-interior-point algorithm, which has to start from a feasible point. We introduce a primal-dual infeasible-interior-point algorithm and prove global convergence of the algorithm. When all the data of the linear programming problem are integers, the algorithm terminates in polynomial-time under some moderate conditions of the initial point. We also introduce a predictor-corrector infeasible-interior-point algorithm, which achieves better complexity and has superlinearly convergence.
