<code class="doc-symbol doc-symbol-heading doc-symbol-function" />

#### invert\_disallowed\_to\_allowed

```python theme={null}
invert_disallowed_to_allowed(disallowed_speaker_transitions_dict: dict[str, list[Agent]], agents: list[Agent]) -> dict[str, list[Agent]]
```

Invert the disallowed\_speaker\_transitions\_dict to form the allowed\_speaker\_transitions\_dict.<br />Start with a fully connected allowed\_speaker\_transitions\_dict of all agents. Remove edges from the fully connected allowed\_speaker\_transitions\_dict according to the disallowed\_speaker\_transitions\_dict to form the allowed\_speaker\_transitions\_dict.<br />
