The past four decades witnessed the birth and growth of neurodynamic optimization, which has emerged as a potentially powerful problem-solving tool for constrained optimization due to its inherent nature of biological plausibility and parallel and distributed information processing. Despite the success, almost all existing neurodynamic approaches a few years ago worked well only for optimization problems with convex or generalized convex functions. Effective neurodynamic approaches to optimization problems with nonconvex functions and discrete variables are rarely available. In this talk, a collaborative neurodynamic optimization framework will be presented. Multiple neurodynamic optimization models with different initial states are employed in the framework for scatter local search. In addition, a meta-heuristic rule in swarm intelligence (such as PSO) is used to reposition neuronal states upon their local convergence to escape local minima toward global optima. Experimental results will be elaborated to substantiate the efficacy of several specific paradigms in this framework for nonnegative matrix factorization, supervised learning, vehicle-task assignment, portfolio selection, and energy load dispatching.
