<strong>Percolation</strong> is a simple model for connectivity on a grid. Each cell is either open or closed.
|
|
This simulation stops as soon as there is a path from the top of the grid to the bottom through the open cells.

In this simulation, cells are randomly opened on a grid. Percolation occurs when there exists
|
|
a connected path of open cells from the top to the bottom of the grid. It is a neat way to visualise
|
|
threshold behaviour: below a certain probability nothing connects, and above it large connected regions
|
|
suddenly begin to appear.

<h3>Technical Details</h3>
|
|
<p>
|
|
The simulation uses a <strong>disjoint-set (Union-Find)</strong> style connectivity algorithm. As random cells open,
|
|
each open cell is union-ed with its open neighbours, and two virtual nodes represent the top and bottom edges
|
|
of the grid. Percolation is detected the moment those two virtual nodes become connected.
|
|
</p>
|
|
<p>
|
|
This makes each update fast and scalable even for larger grids.
