Abstract We illustrate the implementation of a method based on the use of recursion relations in (Bjorken) x-space for the solution of the evolution equations of QCD for all the leading twist distributions. The algorithm has the advantage of being very fast. The implementation that we release is written in C and is performed to next-to-leading order in α_s . Title of program: evolution.c Catalogue Id: ADUB_v1_0 Nature of problem The program provided here solves the DGLAP evolution equations to next-to-leading order α s , for unpolarized, longitudinally polarized and transversely polarized parton distributions. Versions of this program held in the CPC repository in Mendeley Data ADUB_v1_0; evolution.c; 10.1016/j.cpc.2004.03.006 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
