👉 "Steinkirk" is a term used in the field of mathematics, specifically in the context of graph theory. It refers to an instance of a Steiner tree (also known as a Steiner point or Steiner node) where each vertex is connected to exactly two other vertices. A Steiner tree is a tree where every edge connects a vertex with at least two other vertices. The goal of this problem is to find the minimum number of edges required so that no two nodes are adjacent in
