Reconciling a non-binary gene tree with a binary species tree can be done efficiently in the absence of horizontal gene transfers, but becomes NP-hard in the presence of gene transfers. Here, we focus on the special case of endosymbiotic gene transfers (EGT), i.e. transfers between the mit...
We investigate the parameterized complexity of Binary CSP parameterized by the vertex cover number and the treedepth of the constraint graph, as well as by a selection of related modulator-based parameters. The main findings are as follows: Binary CSP parameterized by the vertex cover number is ...
Time complexity is a measure of how fast a computer algorithm (a set of instructions) runs, depending on the size of the input data. In simpler words, time complexity describes how the execution time of an algorithm increases as the size of the input increases. When it comes to finding a...
In streaming, any BFS algorithm that explores k layers of the BFS tree must use at least k/2 passes or Ω(n1+1/k/(logn)1/k) space [4]. Hence, much remains unexplored when it comes to graph exploration- and graph distance-related streaming problems such as BFS/DFS, Diameter, ...
The complexity of sorting problem: O(N log N) 以平衡二元樹、中序法進行排序。 Using balanced binary tree to sort. 平衡二元樹的深度為log2N。 The depth of a balanced binary tree is log2N. 計有N個數字,每個數字最壞的狀況下,要比對log2N次,才能決定其在該二元樹之位置。故共需Nlog2N比對時...
The computation can then be organized as a binary tree in which we add as many pairs of numbers as possible in each time step. The time to compute the addition of n numbers is the height of the tree, so the computation can be done in O(lg n) elapsed time using n/2 processors. ...
The time complexity of the Fibonacci sequence is the number of binary trees;The time complexity of the Fibonacci sequence is the number of times the function call stack is the depth of the binary tree. //斐波那契尾递归算法:(优化) //时间复杂度:O(n) //空间复杂度:O(n) long long Fib(...

In this paper, we focus on the design of binary constant weight codes that admit low-complexity encoding and decoding algorithms, and that have size $$M=2^
