Abstract :
Critic-based approaches and closed-loop optimization are two of the most important fundamental neurocontrol approaches, which can be used in incremental or batch mode. To assess their complexity for the same type of nonlinear control problems, idealized algorithms on a discrete state space are constructed, using a dynamic optimization framework. The comparison of both algorithm complexity and number of data samples necessary to reach the solution is done. Alternative complexity investigation is done by comparing the number of parameters to be instantiated in linear case. The incremental processing turns out to be the less efficient alternative
