主 题:bilevel linear programming local and global optima penalty methods simplex method
摘 要:We analyze the article A modified simplex approach for solving bilevel linear programming problems (EJOR, 67, 116-135). We point out some problems in its theoretical analysis. Moreover, the algorithm proposed may not find a global solution as it is claimed. We give some examples in order to illustrate these remarks. (C) 2000 Elsevier Science B.V. All rights reserved.
