They are better known for their use in such self- balancing varieties as AVL and splay.
The "forgiving" variety of this structure, described in 2008 by Hayes et al, is self-healing, and thus can be used to protect a peer-to-peer network from attack. Any two vertices of these data structures are linked by a unique path, and all nontrivial instance of them contain at least one node with degree one. Also known as acyclic connected graphs, (*) they are employed by parsers to represent syntax, and Prim's algorithm can find the minimum spanning variety of these. They are better known for their use in such self- balancing varieties as AVL and splay. For 10 points, identify these data structures used in heaps and to represent binary searches, whose unions are known as forests.
