title = "A simple dual ascent algorithm for the multilevel facility location problem",
abstract = "We present a simple dual ascent method for the multilevel facility location problem which finds a solution within \$6\$ times the optimum for the uncapacitated case and within \$12\$ times the optimum for the capacitated one. The algorithm is deterministic and based on the primal-dual technique.",
