Prevod v slo (grid scheme)

Ne vem točno kam bi sploh vtaknjiti tole temo.
Uglavnem zadevaja je, da moram pri magistrski prevesti "grid scheme" v slovenščino pa nenajdem nobenega primernega slovenskega izraza. Ima kdo kakšno idejo kako prevesti tole?

Agarwal and Procopiuc develop an approximation algorithm for the geometric f-center problem using a grid scheme which is similar to the one used in Sec. 3
