Mech-Elites: Illuminating the Mechanic Space of GVGAI
  This paper introduces a fully automatic method of mechanic illumination for
general video game level generation. Using the Constrained MAP-Elites algorithm
and the GVG-AI framework, this system generates the simplest tile based levels
that contain specific sets of game mechanics and also satisfy playability
constraints. We apply this method to illuminate mechanic space for $4$
different games in GVG-AI: Zelda, Solarfox, Plants, and RealPortals.
