{wiki=Polyhedral_combinatorics}
Polyhedral combinatorics is a branch of combinatorial optimization that studies the properties and relationships of polyhedra, which are geometric structures defined by a finite number of linear inequalities. In the context of optimization, polyhedral combinatorics primarily focuses on the following aspects: 1. **Polyhedra and Convex Sets**: A polyhedron is a geometric figure in n-dimensional space defined by a finite number of linear inequalities.
