Invasion percolation is a model used in statistical physics and materials science to study the behavior of fluid or other substances infiltrating a porous medium. It is particularly applicable in the analysis of how interfaces between different phases evolve and how materials break or disengage under stress. ### Key Features of Invasion Percolation: 1. **Lattice Representation**: Invasion percolation is often modeled on a lattice or grid, where each site or bond can be occupied or vacant.
