An Analytic Center Cutting Plane Approach for Conic Programming

چکیده
We analyze the problem of finding a point strictly interior to a bounded, fully dimensional set from a finite dimensional Hilbert space. We generalize the results obtained for the LP, SDP and SOCP cases. The cuts added by our algorithm are central and conic. In our analysis, we find an upper bound for the number of Newton steps required to compute an approximate analytic center. Also, we provide an upper bound for the total number of cuts added to solve the problem. This bound depends on the quality of the cuts, the dimensionality of the problem and the thickness of the set we are considering.

An Analytic Center Cutting Plane Method in Conic Programming
Conic programming has been lately one of the most dynamic area of the optimization field. Although a lot of attention was focused on designing and analyzing interior-point algorithms for solving optimization problems, the class of analytic center cutting plane methods was less investigated. These methods are designed to solve feasibility problems by finding points which are interior to differen...
متن کاملA Proximal Analytic Center Cutting Plane Algorithm for Solving Variational Inequality Problems
Under the condition that the values of mapping F are evaluated approximately, we propose a proximal analytic center cutting plane algorithm for solving variational inequalities. It can be considered as an approximation of the earlier cutting plane method, and the conditions we impose on the corresponding mappings are more relaxed. The convergence analysis for the proposed algorithm is also give...
متن کاملAn Analytic Center Cutting Plane Method for Semideenite Feasibility Problems
Semideenite feasibility problems arise in many areas of operations research. The abstract form of these problems can be described as nding a point in a nonempty bounded convex body ? in the cone of symmetric positive semideenite matrices. Assume that ? is deened by an oracle, which for any given m m symmetric positive semideenite matrix ^ Y either connrms that ^ Y 2 ? or returns a cut, i.e., a ...
