... and W(n). What recursion scheme would get us there? The Master theorem Case 1 says if b=4, a=2, then log4 2 =1/2. So if we have something like T(n) = 2T(n/4) + o(√n) we would get O(√n) solution for L(n) and W(n). ...

... Tree: set of nodes storing elements in a parent-child relationship with the following properties: – T has a special node r, called the root of T, with no parent node; – Each node v of T, such that v ≠ r, has a unique parent node u Note a tree cannot be empty (must have root) – Just a convention ...

Quadtree
A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. All forms of quadtrees share some common features: They decompose space into adaptable cells Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits The tree directory follows the spatial decomposition of the quadtree.
