    Analysis of an efficient parallel implementation of active-set Newton algorithm 
    San Juan-Sebastian, Pablo; Virtanen, T.; García Mollá, Víctor Manuel; Vidal Maciá, Antonio Manuel (Springer-Verlag, 2018)
    [EN] This paper presents an analysis of an efficient parallel implementation of the active-set Newton algorithm (ASNA), which is used to estimate the nonnegative weights of linear combinations of the atoms in a large-scale ...
