The data postcomputing (opposite to Data Preprocessing) is applied using dynamic programming principle which starts with only required data and computes only the necessary attributes required to construct Optimal Binary Search Tree with time complexity O(n) if there are n identifiers / integers / ...
Determining Optimal Binary Search Tree is an optimization problem to find the optimal arrangement of nodes in a binary search tree so that average search time is minimized. A Dynamic programming algorithm can solve this problem within O(n)-time complexity and a workspace of size O(n). We ...
Given keys and frequency at which these keys are searched, how would you create a binary search tree from these keys such that the cost of searching is minimum. The cost of searching is defined as the sum of all node's search frequency * its depth; Root node's depth is 1. Solution 1...
For this, we give a polynomial-time reduction from Partition to for the case when distributions Fi's have support (at most) 3. Recall the Partition problem (Garey and Johnson, 1990): Definition 5.1 Partition Input: A set C={c1,…,cn} of n positive integers (encoded in binary). Probl...
At the same time, it employs the joint probability mutation characteristic to randomly search for the global optimal solution of the objective function. K-means: First, it randomly assigns K cluster centers in the mobile communication base station cluster, and divides the base stations to be ...
The bounds were selected to give the algorithm an extensive search domain but excluding known sub-optimal regions that may increase the convergence time. For instance, the A1 term was constrained to negative values to prevent pitch profiles that lead to exceptionally high effective angles of attack...
An analysis of the two-sensor case with binary hypotheses is presented. Since the number of measurements is an integer, an exhaus- tive search (grid search) is traditionally employed to de- termine the optimal allocation of measurements. However, such a search is computationally expensive. To ...
Thresholds and Optimal Binary Comparison Search TreesThresholds and Optimal Binary Comparison Search Treesdoi:10.1016/S0196-6774(02)00203-1We present an O(n4)-time algorithm for the following problem: Given a set of items with known access frequencies, find the optimal binary search tree under the...

Our database consists ofkmax(n) + 1 parts, such that thek-th part contains all elements of\({{{\mathcal{R}}}_{n}^{k}\). The elements are furthermore stored in the lexicographic order to enable binary search. Let\(I\,\in \,{{{\mathcal{C}}}_{n}\)be the identity matri...
