Abstract

In this paper, we discuss the solution of an Inverse Eigenvalue Complementarity Problem (IEiCP). Two nonlinear formulations, NLP1 and NLP2, of the IEiCP are presented. A necessary and sufficient condition for a stationary point of NLP1 to be a solution of the IEiCP is established. On the other hand, for assuring global convergence to a solution of IEiCP when it exists, an enumerative algorithm is designed by exploiting the formulation NLP2. The use of additional implied constraints for enhancing the efficiency of the algorithm is also discussed. Computational results are provided to highlight the performance of the algorithm.
