  • Introduce the -l option to set min block deletion length using powers of 2 (e.g., 1, 2, 4, 8, 16, ...).
  • This enables a trade-off between minimization thoroughness and speed.
  • Adjusting del_len_limit allows for faster processing, as doubling it roughly halves the minimization time.
  • Closes tmin: Proposing del_len option for improved speed #431
