“…Consequently, various primal-dual interior-point algorithms were proposed by different authors; see, e.g., [2,11,16,17,18,19,20,21,22,23] and the references therein. Inspired by Alizadeh [2] and Benterki, Crouzeix and Merikhi [24], the main aim of this paper is to construct a polynomial feasible primal-dual projective interior point algorithm with two phases. The first phase gives an initial strictly feasible solution of (SDP), and the second one gives a primal-dual optimal solution of (SDP) and (DSDP).…”
