Givennkeys (K1,K2,…,Kn), the access probabilities of each key, and those occurring in the gap between two successive keys, an optimal binary search tree for this set of keys is one which has the smallest search cost. The OBST problem is to construct an optimal binary search tree, give...

From the observation that LBP is equivalent to the application of a fixed binary decision tree, Maturana et al. [95] proposed a new method for learning discriminative LBP-like patterns from training data using decision tree induction algorithms. For each local image region, a binary decision tree...
[28], Sine Cosine Algorithm (SCA) [29], and Tree and Species Optimization (TSA) algorithms [30] significantly influence the solution outcomes during the search and optimization phases owing to their initial parameter settings. For instance, although GA exhibits robust global search capabilities, it...
The above formulations can in principle generate certified globally optimal structures. In practice, however, there is a combinatorial explosion in the number of binary variables as the depth of the tree or the size of the dataset increases. Thus, optimality gap can be closed by branch-and-bound...
This way, we recover the result obtained in17 without the need to solve the equations of motion or requiring to find the eigenstates of the system. Binary tree Here we consider our graph to be a binary tree with l levels, where the number of nodes is 2l − 1. The Hamiltonian ...

Given n positive integer weights, can one compute an optimal binary prefix free code in time within 𝑜(min{𝑘𝑛,𝑛log𝑛})o(min{kn,nlogn}) in the algebraic decision tree computational model for some general class of instances? 1.3. Contributions We answer in the affirmative for many...
