Very Large-Scale Singular Value Decomposition Using Tensor Train Networks [PDF]

open access: yes, 2014
We propose new algorithms for singular value decomposition (SVD) of very large-scale matrices based on a low-rank tensor approximation technique called the tensor train (TT) format. The proposed algorithms can compute several dominant singular values and

Large-Scale Path-Dependent Optimization of Supersonic Aircraft

open access: yesAerospace, 2020
Aircraft are multidisciplinary systems that are challenging to design due to interactions between the subsystems. The relevant disciplines, such as aerodynamic, thermal, and propulsion systems, must be considered simultaneously using a path-dependent ...

Improved sine cosine algorithm for large-scale optimization problems

open access: yesShenzhen Daxue xuebao. Ligong ban, 2022
Aiming at the shortcomings of the sine cosine algorithm (SCA) in solving the large-scale optimization problems, such as low accuracy, slow convergence speed, and being easy to fall into the dimension disaster, we propose an sine cosine algorithm with ...

A modified three-term conjugate gradient method for large –scale optimization

open access: yesTikrit Journal of Pure Science, 2020
We propose a three-term conjugate gradient method in this paper . The basic idea is to exploit the good properties of the BFGS update. Quasi – Newton method lies a good efficient numerical computational, so we suggested to be based on BFGS method ...

Modifications of the Limited Memory BFGS Algorithm for Large-scale Nonlinear Optimization [PDF]

open access: yes, 2005
In this paper we present two new numerical methods for unconstrained large-scale optimization. These methods apply update formulae, which are derived by considering different techniques of approximating the objective function.
