| A '''computation tree''' is a representation for the computation steps of a [[non-deterministic Turing machine]] on a specified input. A computation [[tree (graph theory)|tree]] is a [[rooted tree]] of nodes and edges. Each node in the tree represents a single computational state, while each edge represents a transition to the next possible computation. The number of nodes of the tree is the size of the tree and the length of the path from the root to a given node is the depth of the node. The largest depth of an output node is the depth of the tree. The output nodes of the tree are called leaves.

| In a computation tree each output node is labeled Yes or No. If a tree, T, with an input space X, if <math> x \in X </math> and the path for x ends in node labeled yes, then the input x is accepted. Else it is rejected.
| |
| | |
| The depth of the computation tree for a given input is the [[computation time]] for the Turing machine on that input.
| |
| | |
| One of the primary methods of showing that a computational problem ''L'' is [[complete (complexity)|complete]] for a given [[complexity class]] ''C'' is to show that the computation tree of any algorithm in ''C'' can be directly analyzed in terms of ''L''.
