Abstract: This paper investigates the response of two competing species to a given resource using optimal control techniques. We explore the choices of directed movement through controlling the advective coefficients in a system of parabolic partial differential equations. The objective is to maximize the abundance represented by a weighted combination of the two populations while minimizing the `risk' costs caused by the movements.

Keywords:  Optimal control, advection direction, competitive systems, partial differential equations, parabolic system.
