-TODO:
-
-Applications:
-
-- degree-restricted cases and arborescences
-- bounded expansion classes?
-
-Ranking:
-
-- ranking of permutations on general sets, relationship with integer sorting
-- JN: 4.5.1:  neslo by preci isolovat nejaky vlstnosti restriction matrices
-  tak aby byl speedup? Staci napr predpokladat 4.5.2 (jako to postulovat)
-  co je to vlastne za matice co splnuji 4.5.2
-- JN: bounded-degree restriction graphs; would it imply general speedup?
-
-Typography:
-
-- formatting of multi-line \algin, \algout
