Query: Revenue Maximization in an Optical Router Node Using Multiple
  Wavelengths   In this paper, an optical router node with multiple wavelengths is
considered. We introduce revenue for successful transmission and study the
ensuing revenue maximization problem. We present an efficient and accurate
heuristic procedure for solving the NP-hard revenue maximization problem and
investigate the advantage offered by having multiple wavelengths.
