The numerical analysis is aimed to obtain the estimation of a short solenoid equivalent to the unknown magnet. Least squares approach has been used to solve the functional defined as squared sum of the residuals. A comparison of the results obtained with Genetic Algorithm approach and nonlinear system of equations is performed. A regularized solution, which is in good agreement with the experimental data, was found by applying a Newton adapted regularization technique.}, type={Artykuły / Articles}, title={Estimation of an equivalent short solenoid model using different numerical methods}, URL={http://so.czasopisma.pan.pl/Content/84578/PDF/04_paper.pdf}, doi={10.2478/v10171-011-0036-1}, keywords={solenoid model, nonlinear problem, numerical methods, least squares}, }
