Colours of enabled operations: Difference between revisions

Latest revision as of 08:07, 6 January 2012

The enabled operations are shown in different colours, depending on the state where the operation leads to. If more than one rule of the following list apply, the first colour is taken:

blue: The operation does not change the state (behaves like skip).
green: The operation leads to a new, not yet explored state.
red: The operation leads to a state where the invariant is violated.
orange: The operation leads to a deadlock state, i.e. a state where no operation is enabled.
black: Otherwise, the operation leads to a state that is different to the current state, has already been visited and is neither an invariant violating or deadlock state.
