In a way, this distinguishes it from the hidden subgroup problem where more stringent requirements about the existence of a periodic subgroup have to be made. And yet, the hidden s

If squares are non-overlapping and of different sizes, the time complexity of the best known algorithm is .(..). If squares are allowed to overlap but have the same size, the time complexity of the best known algorithm is .(..). In this

Cograph Editing: Complexity and Parameterized Algorithms,nal complexity of this problem was open in the past. In this paper, we show that this problem is NP-hard, and present a parameterized algorithm based on a refined search tree technique with a running time of .(4.612. + |.|.)), which improves the trivial algorithm of running time .(6. + |.|.).

Dominating Set Counting in Graph Classes,ynomial-time algorithms to count the number of dominating sets (and minimum dominating sets) in interval graphs and trapezoid graphs. They are based on dynamic programming. With the help of dynamic update on a binary tree, we further reduce the time complexity. On the other hand, we prove that count

FlipCut Supertrees: Towards Matrix Representation Accuracy in Polynomial Time,erent ways, to cope with contradictory information in the input. In particular, there exist methods based on encoding the input trees in a matrix, and methods based on finding minimum cuts in some graph. Matrix representation methods compute supertrees of superior quality, but the underlying optimiz
