(Irregular) Grids
One common way to deploy nodes in a bidimensional space is on a grid.
Grid-like deployments can be easily performed in Alchemist
leveraging the Grid Deployment.
The following example shows a grid centered in (0, 0),
with nodes distanced of 0.25 both horizontally and vertically.
Often, symmetric structures may induce corner behaviors in self-organising systems,
and real-world “grid” deployments are not usually geometrically perfect.
Indeed, it is common to perturb the grid shape randomly,
in order to account for potential irregularities of the real-world system
being simulated.
Grid supports perturbation natively:
for instance, here is an example of a grid where positions are
randomly perturbed of ±0.1 distance units.
