[7], however, designed a linear-time algorithm for domination in trees which has inspired us to pursue a linear algorithm for finding MSDSs of trees in this paper. The advantage of having a fast algorithm for c
Red–black trees, like allbinary search trees, allow efficientin-order traversal(that is: in the order Left–Root–Right) of their elements. The search-time results from the traversal from root to leaf, and therefore a balanced tree ofnnodes, having the least possible tree height, results in...
In order to build a CDS, most of the proposed algorithms are to find an MIS and then to connect this set. Note that in an undirected graph, an MIS is also a DS. In [28], Wan et al. proposed a distributed algorithm for constructing a CDS in an UDG. The algorithm consists of two...
An important reason why Problem (1) worked beautifully was because the dfs-order traversal made it possible to represent any subtree as a contiguous range in an array. Thus the problem was reduced to "finding number of distinct values in a subarray[L, R]ofA[].Note that it is not possi...
Due to the swift advancement of the Internet of Things (IoT), there has been a significant surge in the quantity of interconnected IoT devices that send and exchange vital data across the network. Nevertheless, the frequency of attacks on the Internet of
After a period of time, case (3) will naturally transition to case (1). To minimize the traversal of each EACV in the block, the system will write the expiration time \(t_f\) of the last EACV in each side block. When the system time \(t > t_f\), the system will ...

This labeling scheme (called region encoding) uses a region code (start,end,level) to represent the position of an XML element in the data tree where start and end are generated by performing a pre-order traversal procedure of the data tree; level is the nesting depth of the element in ...
