Popis:	The aim of our approach is a reliable numerical approximation of quasi-periodic solutions of periodically forced ODEs without using a-priori transformations into new coordinates [1]. The invariant torus is computed as a solution of a special invariance equation. In the case of two basic frequencies this system can be solved by semidiscretisation, which transforms the system into a higher dimensional autonomous ODE system with periodic solutions.
