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