N2 - The purpose of this work was to find the optimal configuration for an off-grid, renewable energy reverse osmosis (RO) desalination system using an ant system (AS), where the objective was to find the lowest annualized cost of the renewable energy system. This nonlinear integer programming was transferred to finding the shortest route on the construction graph by artificial ants. A well on the Navajo Nation in Arizona, USA was selected as the candidate site and real-world data were used. The capacity of the RO system was 18.93 m^{3}/d (5000\ gal/d), requiring a constant power consumption of 3.95 kW. The results of the AS optimization showed that the optimal configuration with the smallest annualized cost of the renewable energy system was a hybrid wind/photovoltaic/battery system, although a diesel generator was a candidate. The cost of energy was 0.46 USD/ kWh and cost of water was 3.35 USD/m^{3}, which was less than half of the 7.9 USD/m^{3} currently paid by residents that live in the area.
