Computational science in the eighteenth century. Test cases for the methods of Newton, Raphson, and Halley: 1685 to 1745
Steihaug, Trond (Peer reviewed; Journal article, 2020)This is an overview of examples and problems posed in the late 1600s up to the mid 1700s for the purpose of testing or explaining the two different implementations of the Newton-Raphson method, Newton’s method as described ... -
Generating a synthetic diffusion tensor dataset
Bergmann, Ørjan; Lundervold, Arvid; Steihaug, Trond (Peer reviewed; Journal article, 2005)During the last years, many techniques for de-noising, segmentation and fiber-tracking have been applied to diffusion tensor MR image data (DTI) from human and animal brains. However, evaluating such methods may be difficult ... -

Steihaug, Trond; Rogers, D. G. (Peer reviewed; Journal article, 2009) -
A New Generating Set Search Algorithm for Partially Separable Functions
Frimannslund, Lennart; Steihaug, Trond (ADVCOMP 2010 : The Fourth International Conference on Advanced Engineering Computing and Applications in Sciences, Conference object; Peer reviewed, 2010)A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ... -
On a New Method for Derivative Free Optimization
Frimannslund, Lennart; Steihaug, Trond (Peer reviewed; Journal article, 2011)A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ... -
