Students are introduced to basic solution methods for problems dependent on random input variables and for estimating of models and their parameters from measured data. The subject focuses on the computational properties of these methods, related numerical methods, their convergence conditions and efficiency. The particular topics are numerical solution of determinic partial differential equations, finite element method, finite difference method (only a sketch of them both); basic methods of computational probability; partial differenetial equations with random parameters; Monte Carlo Method; collocation method; stochastic Gallerkin method; solution spaces of problems with random data; Karhunen-Loeve expansion; Mercer’s lemma; covariance matrix decomposition; convergence with respect to random variables; Bayesian methods; inverse analysis.
