We performed simulations with 15, 25, and 35 users
respectively. For each user, the energy requirement is uniformly
distributed between 0 to 10KWh. Figures 2 a) and 2 b) show the
Pareto optimal solutions obtained by EMOCA and SPEA-II for
15 users. We observe that higher utility is achieved with an
increase in energy cost. The figures show that EMOCA obtains
multiple diverse solutions characterizing the trade offs between
energy cost and utility. We observe that EMOCA outperforms
SPEA-II in terms of solution quality and diversity
