“…Malibari et al 30 present a review only on energy saving with the help of coalition formation in MAS. Ayachi et al 31 discuss various forms of coalition formation, for example, grand coalition, optimal CSG, coalition formation under the influence of externalities, disjoint coalition, and overlapping coalition.
