Abstract: Let $\pi$ be an underlying probability (density) known up to a norming constant, Markov processes (chains), regarded as 'conceptual algorithms', may be used to approximate sample from $\pi$. The evaluation of the approximation is investigated under various comparison criteria, e.g. asymptotic variance, spectral gap, convergence exponent in variational norm. The worst-case analysis, the average-case analysis, uniform comparison, antisymmetric perturbations are considered. Some related problems in analysis and geometry are discussed. This is a survey of our work.
