This section covers all of the basic topology variables that describe the structure of the world.

WORLD_X WORLD_Y

The settings determine the size of the Avida grid that the organisms populate; the world consists of WORLD_X * WORLD_Y cells. In mass action mode the shape of the grid is not relevant, only the number of organisms that are in it.

See the avida.cfg file for more settings: WORLD_GEOMETRY, SCALE_FREE, SCALE_FREE_ALPHA, and SCALE_FREE_ZERO_APPEAL.
