👉 In computational complexity theory, a "helotery" (also known as a "hitting set" or "hit-and-run") is a subgraph of a graph that contains all vertices with minimum degree. Heloteries are an important concept in graph theory and have applications in algorithms for finding shortest paths between two nodes. In the context of computational complexity, a helotery is a special type of graph called a directed acyclic graph (DAG), which means it has no cycles.
