What it shows

  • Depth-first search traverses the wait-for graph to spot cyclic locks.
  • Victim selection chooses tasks with minimal work done to reduce rollback.
  • Aborting the victim releases acquired locks so other threads progress.

The takeaway

Deadlock detection resolves circular waits by identifying graph cycles and aborting a low-cost victim.
