This thesis is composed of two parts. The first part focuses on Sequential Monte Carlo samplers, a family of algorithms to sample from a sequence of distributions using a combination of importance sampling and Markov chain Monte Carlo (MCMC). We propose an improved version of these samplers which exploits intermediate particles created by the application of multiple MCMC steps. The resulting algorithm has a better performance, is more robust and comes with variance estimators. The second part analyses existing and develops new smoothing algorithms in the context of state space models. Smoothing is a computationally intensive task. While rejection sampling has been proposed as a solution, we prove that it has a highly variable execution time...
