The -principal points of a random variable with finite second moment are those points in minimizing the expected squared distance from to the closest point. Although the determination of principal points involves in general the resolution of a multiextremal optimization problem, existing procedures in the literature provide just a local optimum. In this paper we show that standard Global Optimization techniques can be applied.

En el presente trabajo establecemos una nueva aproximación a la solución del problema de localización con normas mixtas a través de las direcciones de proyección.
Probamos que el cierre octogonal de los puntos de demanda es una buena aproximación para el conjunto de puntos eficientes cuando el problema está formulado como un problema multiobjetivo con normas mixtas tipo lp. Demostramos que esta cota es alcanzable, dando condiciones para que...
