The fits of all published data on g1, including the new COMPASS measurements of g{sub 1}{sup d}(x,Q{sup 2}), have been performed by using two different QCD evolution formalisms in the next-to-leading-order (NLO) approximation. In both methods we obtain two solutions for fitted parameters of the parton distribution functions (PDFs), one with {delta}G>0 and the other - with {delta}G<0, where {delta}G is the first moment of the polarized gluon distribution in nucleon.
