The proposed algorithm in this article is an advancement of alternating projections method for convex programming. It can efficiently solve combinatorial optimization problems in polynomial time. Additionally, it is a Fully polynomial time approximation Scheme for a wide range of optimization problems with an exponential or infinite number of constraints.
This article proposes an algorithm for convex programming which can be viewed as a further development of the method of alternating projections. Some combinatorial problems like the maximum matchings and the maximum simple b-matchings can be solved in polynomial time by this algorithm. More generally, it runs in polynomial time for any binary linear problem where the objective function is defined by a binary vector and the convex hull of the feasible set can be described by a system of the form Ax <= b, x >= 0, given by a polynomial-time separation oracle, where A is a nonnegative matrix. Also, our algorithm is an Fully polynomial time approximation Scheme for a wide range of optimization problems with an exponential or infinite number of constraints given by a separation oracle.
