- Article in a SIAM journal, invited by its editor-in-chief Sturmfels (Berkeley) and based on conference papers in top venues (SODA'17, ICALP(B)'16). Cited in the SIAM Activity Group on Optimization newsletter [SIAG/OPT Views and News 25(1), 2017] by Gillis, an ERC Starting Grant holder, as having "answered an important open problem" on nonnegative matrix factorisation posed by J.E.Cohen (Columbia and Rockefeller) and U.G.Rothblum (Technion) two decades ago - before NMF became a standard instrument in machine learning (see, e.g., Lee and Seung, Nature (1999); Arora et al., FOCS'12). G.Rote (FU Berlin) presented a follow-up open problem at Oberwolfach [Report 19/2017].
