+Breadth First Search is an algorithm for searching a tree/graph for a node that
+has a certain property. It starts at some chosen/implied root node, and
+traverses the entire tree/graph. Therefore, BFS is often performed in O(n)
+time. 
+
+== Algorithm ==

+=== Tree ===
+
+The algorithm first starts by creating a Queue, Q, and a pointer to the current
+node, curr. Starting at the root of the tree, all child nodes of the current
+node are placed onto Q, then curr is changed to the first element of Q, which
+is dequeued. This will traverse the tree from left to right, layer by layer. If
+desired, a condition can be added for the desired node. 
+
+This method of traversal *does not* take advantage of the structure of a tree,
+and therefore does not have any of the lookup advantages of a [[binary_tree]].
