Matrix Algebras in Quasi - Newtonmethods for Unconstrained
In this paper a new class of quasi-Newton methods, named LQN, is introduced in order to solve unconstrained minimization problems. The novel approach, which generalizes classical BFGS methods, is based on a Hessian updating formula involving an algebra L of matrices simultaneously diagonalized by a fast unitary transform. The complexity per step of LQN methods is O(n log n), thereby improving c...
متن کاملNew three-step iteration process and fixed point approximation in Banach spaces
In this paper we propose a new iteration process, called the $K^{ast }$ iteration process, for approximation of fixed points. We show that our iteration process is faster than the existing well-known iteration processes using numerical examples. Stability of the $K^{ast}$ iteration process is also discussed. Finally we prove some weak and strong convergence theorems for Suzuki ge...
متن کاملCoincident point and fixed point results for three self mappings in cone metric spaces
In this attempt we proved results on points of coincidence and common xed points for three selfmappings satisfying generalized contractive type conditions in cone metric spaces. Our results gen-eralizes some previous known results in the literature (eg. [5], [6])
متن کاملConjugate Grids for Unconstrained Optimisation
Several recent papers have proposed the use of grids for solving unconstrained optimisation problems. Grid-based methods typically ge:nerate a sequence of grid local minimisers which converge to stationary points under mild conditions. The location and number of grid local minimisers is calculated for strictly convex quadratic functions in two dimensions with certain types of grids. These calcu...
متن کاملSome results on coupled fixed point and fixed point theory in partially ordered probabilistic like (quasi) Menger spaces
In this paper, we define the concept of probabilistic like Menger (probabilistic like quasi Menger) space (briefly, PLM-space (PLqM-space)). We present some coupled fixed point and fixed point results for certain contraction type maps in partially order PLM-spaces (PLqM- spaces).
