2021-03-14Adding sorting on tuples. (#720)jouvelot
* Adding sorting on tuples. Co-authored-by: Cyril Cohen <CohenCyril@users.noreply.github.com>
2021-03-08Adding big block matricesCyril Cohen
- with special cases for row, column, and diagonal matrices - we define an order bijection between the indexing of the whole matrix and the indexing of the blocks to preserve triangularity

2020-11-19Refactor, reshuffle, and rename sorting lemmas in `path.v`Kazuhiko Sakaguchi
- Lemmas `sorted_(lt|le)_nth` have been renamed to `sorted_(ltn|leq)_nth`. - Lemmas `(ltn|leq)_index` have been renamed to `sorted_(ltn|leq)_index` and generalized for non-`eqType`s. - Lemmas `order_path_min`, `path_sortedE`, `subseq_order_path`, `subseq_sorted`, `sorted_uniq`, `sorted_eq`, `irr_sorted_eq`, `sorted_(ltn|leq)_nth`, and `sorted_(ltn|leq)_index` have been relocated since their proofs are independent from `merge` and `sort`. - The stability proofs for `iota` sequences (`push_stable`, `pop_stable`, and `sort_iota_stable`) have been simplified by sorting out their hypotheses and by redefining `push_invariant` to include the `sorted` condition. Their main result `sort_iota_stable`, formerly a local `Let` to prove `sort_stable`, has been turned into a lemma. - Some stability proofs for general sequences (`sort_stable` and `filter_sort`) have also been simplified, of which the former one uses the above `sorted_ltn_nth` lemma for a non-`eqType`.

2020-11-18Adding size_merge_sort_pushCyril Cohen
This documents the fact that `merge_sort_push` preserves an invariant on its second argument. Importing a statement and proof by Georges Gonthier, inspired by one of Karl Palmskog's contribution.

- Rename `eq_sorted` lemmas to `sorted_eq` to address a naming inconsistency. - Lemma `sort_le_id` has been generalized from `orderType` to `porderType`.

2020-11-12Adding some theory for `rem` and generalizing `subset_maskP`Cyril Cohen
- Added helper lemmas about `rem`: `rem_cons` (to control unfolding), `remE`, `count_rem`, `count_mem_rem`, and `subseq_mem`. (New lemma `drop_index` briges the gap between `cat_take_drop` and `remE`). - `subset_maskP`, which was not released yet is generalized with hypothesis `(forall x, count_mem x s1 <= count_mem x s2)`, instead of `uniq s1` and `{subset s1 <= s2}`, the previous behaviour can be restored with helper lemma `leq_uniq_count` - Its trivial consequence `subset_subseqP` has been added too.

2020-11-10Reorganize, generalize, and add lemmas about `path`, `cycle`, and `sorted`Kazuhiko Sakaguchi
- Add `allss` and `all_mask` lemmas. - Since `path`, `cycle`, and `sorted` share similar properties, these lemmas have been relocated in the same place to improve the visibility. Some missing lemmas have also been discovered and added. - Generalize `sub_path_in`, `sub_sorted_in`, and `eq_path_in` for non-`eqType` T by introducing a predicate `P : {pred T}`.
