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 ...
Implemented as a VLSI array, the algorithm for building the optimal BST uses O(n) processors and has the parallel time complexity O(n). A search is solved in O(log n) time. On a cluster of computers, the binary search tree is organized on two levels: the first level corresponds to ...
Elevated ability to escape from local optima. The specular reflection learning strategy in GEO-DLS simulated the behavior of light on a mirror surface, introducing the reflection and rebound effects to enhance the search path. This feature enabled the algorithm to escape from local optimal solutions ...

The 𝑁𝑇𝐷𝐿NTDL outputs are summed together, using a tree adder with ⌈𝑙𝑜𝑔2(𝑁𝑇𝐷𝐿)⌉⌈log2(NTDL)⌉ pipeline stages (i.e., 1 for 𝑁𝑇𝐷𝐿=2NTDL=2, 2 for 𝑁𝑇𝐷𝐿∈{3;4}NTDL∈{3;4}, 3 for 𝑁𝑇𝐷𝐿∈{5;6;7;8}NTDL∈{5;...
Thus, it is vital to decrease the time complexity, and some techniques have been developed to get fast exact algorithms for NP-hard problems, including pruning the search tree, improved data processing method, local search, and dynamic programming across the subsets (Woeginger, 2003). Some of ...
We present an ()-time algorithm for the following problem: Given a set of items with known access frequencies, find the optimal binary search tree under the realistic assumption that each comparison can only result in a two-way decision: either an equality comparison or a less-than comparisons...
we also prove almost optimal computational complexity. In particular, we provide an additive Schwarz preconditioner which can be computed in linear complexity and which is optimal in the sense that the condition numbers of the preconditioned systems are uniformly bounded. As model problem serves the ...
