The Cold Start User-Item Model (CSUIM) of a bipartite graph is considered. which simulates bipartite graph growth based on several parameters. An algorithm is proposed to compute parameters of this model with desired properties. https://www.nacrack.com/mega-pick-As-for-Me-and-My-House-Wall-Decal-in-Hebrew-Yahauh-flash-find/
