Function $f_g()$ to generate possible subsets of Grid machines to allocate tasks to.

ObjectiveType	Function $f_g(W_G[1,...,m],p[1,...,m],objectiveType)$
GS	Generate all possible combinatorial subset of grid-machines
GCCS	Generate combinations of grid-machines with all the machines in each subset belonging to the same grid
GECS	Generate combinatorial subsets of all grid-machines that offer the lowest execution price (Ignore other Grid-Machines)
GNFS	Generate singleton subsets of all the grid-machines
