For future reference: It would be very convenient if we could support instantiations checkers for non-graph preserving assignments; potentially via a flag that must be set explicitly and which leads...

What is the right way to force an MDP to being a DTMC, without much overhead? That is, if I have an MDP (e.g., after applyScheduler with a full scheduler)...

enhancement

Bitvector assignments sometimes require reallocations. This is currently done very conservatively, see a discussion in https://github.com/moves-rwth/storm/pull/189. Before we invest time here, it would be good to understand to what extend...

enhancement

Multiple operations on programs visit all expressions either to modify or to analyse them. This yields a series of awkward code duplications that could be reduced by adding a visitor...

source code enhancement
good first issue

Action masks allow to reduce the edges that we explore during model building, this can drastically reduce overhead in the next-state-generator during simulation.

enhancement

Various method in storm-pomdp currently miss tests; In particular, the transformations, the nondeterministic belief-tracker, the observation trace unfolded. Some of the qualitative analysis methods have very limited tests.

Hi, when trying to combine policy iteration with state elimination, I run into the following bug. Is this combination of methods somehow not a good idea, or does this force...
