LCC: Use the optimized version again, and fix the problem that caused the recent bug. #202

Closed pcostanza closed 1 year ago

pcostanza commented 1 year ago

The recent bug was not in LCC itself, but caused by the call site not caching the required information (nself_edges and is_symmetric_structure). This patch reintroduces the improved LCC version and adds a check whether the required information is indeed cached.
