N2 - Particle filters, as a kind of non-linear/non-Gaussian estimation method, are suffered from two problems when applied to cases with large states dimensions, namely particle impoverishment and sample size dependency. Previous papers from the authors have proposed a novel particle filtering algorithm that incorporates Ant Colony Optimization (PF ACO), to alleviate effect induced by these problems. In this paper, we will provide a theoretical foundation of this new algorithm. A theorem that validates the PF ACO introduces a smaller Kullback-Leibler Divergence between the proposal distribution and the optimal one when comparing to those produced by the generic PF is discussed.
