Optimum site selection is a pretty common problem, for example, when planning shop or warehouse locations or when looking for a new apartment.

  • Locations are close to an elementary school (up to 500 m)

  • Locations are within a reasonable distance (up to 2 km) from a high school

  • Locations are at least 1 km from a main road
