英文摘要: This project focuses on hot-spots of recent research on ODE-based numerical methods for nonlinear optimization: ODE-based hybrid method for unconstrained optimization based on the nomonotone technique; ODE-based hybrid method for large scale unconstrained optimization that combines the trust region and subspace techniques; ODE-based hybrid method for some combinatorial optimization problems; ODE-based hybrid method for solving general constrained optimization that combines the idea of SQP methods and some optimization techniques; ODE-based trust region method for stochastic multiobjective programming. The goal of this project is to promote the research and development of nonlinear optimization methods. These expected achievements should have not only scientific significance,but also wide applications in many fields.
