Abstract
The input for the hotlink assignment problem consists of a node weighted directed acyclic graph with a designated root node r. The goal is to minimize the weighted shortest path length rooted at r by adding a restricted number of outgoing arcs (hotlinks) to each node. The (h, k)-hotlink assignment problem is defined on k-regular complete trees, and at most h hotlinks can be assigned to each node.We contribute algorithms for the (1, k), (2, k), and (k-1, k) hotlink assignment problem.
