Rostislav Stanek (TU, advisor E. Dragoti-Cela): A special case of the data arrangement problem on binary trees

Abstract: The data arrangement problem on regular trees (DAPT) consists of assigning the vertices of a given graph G to the leaves of a d-regular tree T such that the sum of the pairwise distances of all pairs of leaves in T which correspond to edges of G is minimised. Luczak and Noble have shown that this problem is NP-hard for every fixed d ≥ 2. The question about the computational complexity of the DAPT in the case where the guest graph is a tree is still open.
We deal with one special case of this problem where both the guest and the host graph are binary regular trees. Using the k-balanced partitioning problem as a tool, we provide an upper bound, a lower bound, and an approximation algorithm.[hide abstract]
