M-tensors and The Positive Definiteness of a Multivariate Form
M-tensors eigenvalue algorithm positive definiteness
2012/3/1
We study M-tensors and various properties of M-tensors are given. Specially, we show that the smallest real eigenvalue of M-tensor is positive corresponding to a nonnegative eigenvector. We propose an...
A MODIFIED BFGS FORMULA MAINTAINING POSITIVE DEFINITENESS WITH ARMIJO-GOLDSTEIN STEPLENGTHS
2007/12/11
The line search subproblem in unconstrained optimization is concerned
with finding an acceptable steplength satisfying certain standard
conditions. The conditions proposed in the early work of
Armi...
