A sparse quasi-Newton update derived variationally with a nondiagonally weighted Frobenius norm

Ph. L. Toint

Abstrak

The problem of symmetric sparse updating is considered from a variational point of view and a new class of sparse symmetric quasi-Newton updating formulae is derived. This class results from the use of a nondiagonally weighted Frobenius norm. The computation of the update involves only one positive definite and symmetric linear system that has the same sparsity pattern as the problem itself.
