Optimal Binary Search Tree

Optimal Binary Search Tree. We now want to focus on the construction of binary search trees for a static set of identifiers. And only searches are performed. To find an optimal binary search tree for a given static file, a cost measure must be determined for search trees.

ALGORITHM TYPES

ALGORITHM TYPES. Greedy, Divide and Conquer, Dynamic Programming, Random Algorithms, and Backtracking. Note the general strategy from the examples. The classification is neither exhaustive (there may be more) nor mutually exclusive (one may combine).

Optimal Binary Search Tree

Optimal Binary Search Tree. Rytas 12/12/04. 1.Preface. OBST is one special kind of advanced tree. It focus on how to reduce the cost of the search of the BST. It may not have the lowest height ! It needs 3 tables to record probabilities, cost, and root. 2.Premise.

Different Tree Data Structures for Different Problems

Different Tree Data Structures for Different Problems. Data Structures. Data Structures have to be adapted for each problem: A specific subset of operations (Example: Search is needed, Insert is not) A specific set of requirements or usage patterns
