On Dynamically Generating Relevant Elementary Flux Modes in a Metabolic Network using Optimization
Hildur Æsa Oddsdóttir, Erika Hagrot, Véronique Chotteau +1
Elementary flux modes (EFMs) are pathways through a metabolic reaction network that connect external substrates to products. Using EFMs, a metabolic network can be transformed into…
On solving symmetric systems of linear equations in an unnormalized Krylov subspace framework
Anders Forsgren, Tove Odland
In an unnormalized Krylov subspace framework for solving symmetric systems of linear equations, the orthogonal vectors that are generated by a Lanczos process are not necessarily o…
On the connection between the conjugate gradient method and quasi-Newton methods on quadratic problems
Anders Forsgren, Tove Odland
It is well known that the conjugate gradient method and a quasi-Newton method, using any well-defined update matrix from the one-parameter Broyden family of updates, produce identi…
An elementary proof of linear programming optimality conditions without using Farkas' lemma
Anders Forsgren, Margaret H. Wright
Although it is easy to prove the sufficient conditions for optimality of a linear program, the necessary conditions pose a pedagogical challenge. A widespread practice in deriving…
