| Research Abstract |
The complementarity problem is a problem to find a non negative vectors (x, y) which satisfy the equality constraint y=f(x) and the complementarity condition. While some pseudo polynomial-time algorithms have been developed for monotone mappings f, it is known diet the problem with a PO mapping f is NP-complete even if f is linear. However, many problems arising from the real world have been formulated into PO complementarily problems. The aim of the research is to develop some efficient algorithms for solving these practical but non-monotone complementarity problems. To attain it, we provide a homogeneous, interior point method which can be applicable to the complementarity problems with PO functions, derive its theoretical properties and develop a practical algorithm. We consider that we have attained the aim of the research by providing a new algorithm leaving some desirable properties concerning its convergence
