The pos/neg-weighted median problem on block graphs with subgraph-shaped customers

  • Xiaoqin Zhang
  • Liying Kang
  • Yukun Cheng


In this paper we consider the pos/neg weighted 1-median problem on block graphs where the customers are modeled as subgraphs. Under the condition that the block graph has unit edge lengths and the median is restricted to the vertex of the block graph, we devise a linear time algorithm for this problem.
