In this paper, based on the minimax regret model which is an approach for the robust optimization, we consider 1-center problems in weighted and undirected graphs. In an input graph, the weight of a vertex is given as a positive function in time and the length of an edge is given as a positive value. At time t, the weighted distance of v w.r.t. x is defined as the product of the shortest distance from v to x and the weight of v, and the location cost of x is defined as the maximum weighted distance w.r.t. x. The regret of x at time t is defined as the value subtracted the optimal location cost at t from the location cost of x at t. Our aim is to find the location which minimizes the maximum regret over time. We present polynomial time algorithms for the problems on paths and trees. |
