      abstract     = {The properties of a cognitive, self-propelled, and
                      self-steering particle in the presence of a stationary
                      target are analyzed theoretically and by simulations. In
                      particular, the effects of confinement in competition with
                      activity and steering are addressed. The pursuer is
                      described as an intelligent active Ornstein-Uhlenbeck
                      particle (iAOUP), confined in a harmonic potential. For the
                      free pursuer, we find universal scaling regimes for the
                      pursuer-target distance in terms of the Péclet number and
                      maneuverability. Steering results in a novel constant
                      mean-distance regime, which broadens with increasing
                      maneuverability. Confinement strongly affects the propulsion
                      direction and leads to a scaling at large Péclet numbers
                      similar to that in the absence of confinement, yet with a
                      pronounced dependence on confinement strength.},
