Here, we derive the exact mean and variance of number weakly protected nodes (the that are not leaves at least one their children is a leaf) in binary search trees grown from random permutations. Furthermore, by using contraction method, prove normal limit law for properly normalized version this tree parameter.

In this case design application Binary Search Algorithm for processing Pharmacy Isna Farma data made. program aims facilitate drug pharmacies, so that available supply can be controlled by owner. search using keyword words or code. p...

Abstract The feature selection (FS) process has an essential effect in solving many problems such as prediction, regression, and classification to get the optimal solution. For problems, selecting most relevant features of a dataset leads better accuracy with low training time. In this work, hybrid binary crow search algorithm (BCSA) based quasi-oppositional (QO) method is proposed FS on wrappe...

Efficient implementations of sets and maps (dictionaries) are important in computer science, and balanced binary search trees are the basis of the best practical implementations. Pedagogically, however, they are often quite complicated, especially with respect to deletion. I present complete code (with justification and analysis not previously available in the literature) for a purely-functiona...
