A Lagrangean Relaxation Approach for a Turbine Design Quadratic Assignment Problem
本文展示了如何利用拉格朗日松弛方法解决涡轮设计问题，由于问题的特殊结构，松弛后的子问题求解相对简单。
In this paper we show how a Lagrangean relaxation approach to a turbine design problem results in a relatively easy set of Lagrangean subproblems to solve, because of the particular structure of the turbine design problem.
