Loop-erased random walk (LERW) is a mathematical construct and a type of random walk that is particularly interesting in the fields of probability theory and statistical mechanics. It can be thought of as a model for exploring the behavior of paths in a random environment while avoiding certain obstacles (loops). Here's how it works: 1. **Random Walk**: Begin with a simple random walk on a lattice (for example, the integer grid in two dimensions), starting from an origin point.
