The update kills and reduces singular values of I − AH and thus speeds up the convergence. The algorithm terminates after at most n sweeps, and if all n sweeps are needed, then A −1 has been computed.doi:10.1016/0024-3795(89)90719-2Timo Eirola...
Even for a positive-definite, quadratic function with no constraints, it is possible that the symmetric rank-one update may not be defined at some iteration. In this paper, we first demonstrate that such failures of definition correspond to either losses of independence in the directions of ...

The symmetric rank-one update method is well-known in optimization for its applications in the quasi-Newton algorithm. In particular, Conn, Gould, and Toint proved in 1991 that the matrix sequence resulting from this method approximates the Hessian of the minimized function. Expanding their idea...
Let x, y be random vectors of dimension n and yx^{*} be rank-one update of A. Test bounds (10) in Theorem 2.1 according to the three cases 2\leq k\leq n-1, k=n, and k=1. In Tables 1–6, we give the lower and upper bounds determined by (10) for the above three cases...

In each iteration, we pursue a rank-one matrix basis generated by the top singular vector pair of the current approximation residual and update the weights for all rank-one matrices obtained up to the current iteration. We further propose a novel weight updating rule to reduce the time and ...
