This work aims to study and adapt numerical methods for Markov jump linear systems. This is an important class of systems that provide useful models for applications featuring abrupt changes of behavior. Moreover, there are several strong results available in literature, that resemble the ones of standard deterministic linear systems. In this work we focus on an adaptation of the classical variational method: instead of updating the gains stage by stage, we propose to update them in groups of stages, and to study the influence in terms of the computational performance. We will also look into the implementation of a biquadratic method for the gain update. (AU)
