  • The paper provides the high dimensional optimal problem from which the RELAX algorithm is derived, and compares the RELAX algorithm with the alternating projection algorithm from some aspects. Based on the discussion, an improved RELAX algorithm is proposed. The computer simulation confirms the theory is validity.
