3.2. Which global constraints are missing?

Constraints with too many arguments (like for instance the original 𝚌𝚢𝚌𝚕𝚎 [Cosytec97] constraint with 16 arguments), which are in fact a combination of several constraints, were not directly put into the catalogue. Constraints that have complex arguments were also omitted. Beside this, the following constraints should be added in some future version of the catalogue: 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚘𝚗_𝚖𝚞𝚕𝚝𝚒𝚜𝚎𝚝𝚜 [QuimperWalsh05] [QuimperWalshReport05], 𝚌𝚊𝚜𝚎 [Sicstus95], [Carlsson06], [ChengYap05], [ChengYap06], 𝚌𝚑𝚘𝚚𝚞𝚎𝚝 [LeHuedeGrabischLabreucheSaveant06], 𝚌𝚘𝚜𝚝_𝚛𝚎𝚐𝚞𝚕𝚊𝚛 [DemasseyPesantRousseau06], 𝚌𝚞𝚖𝚞𝚕𝚊𝚝𝚒𝚟𝚎_𝚝𝚛𝚊𝚙𝚎𝚣𝚎 [PoderBeldiceanuSanlaville04], [BeldiceanuPoderPMS04], 𝚍𝚎𝚟𝚒𝚊𝚝𝚒𝚘𝚗 [SchausDevilleDupontRegin07], [SchausDevilleDupont07], 𝚒𝚗𝚎𝚚𝚞𝚊𝚕𝚒𝚝𝚢_𝚜𝚞𝚖 [ReginRueher00], [ReginRueher05], 𝚖𝚒𝚗𝚒𝚖𝚞𝚖_𝚜𝚙𝚊𝚗𝚗𝚒𝚗𝚐_𝚝𝚛𝚎𝚎 [DoomsKatriel06], [Regin08], 𝚗𝚘_𝚌𝚢𝚌𝚕𝚎 [CaseauLaburthe97], 𝚛𝚊𝚗𝚐𝚎 [BessiereHebrardHnichKiziltanWalsh05IJCAI], [BessiereHebrardHnichKiziltanWalsh06], 𝚛𝚎𝚐𝚞𝚕𝚊𝚛 [Pesant04] [CoteGendronRousseau07], 𝚜𝚘𝚏𝚝_𝚐𝚌𝚌_𝚟𝚊𝚕 [HoevePesantRousseau04], [HoevePesantRousseau06], [ZanariniMilanoPesant06], [SchausVanHentenryckZanarini10], 𝚜𝚘𝚏𝚝_𝚐𝚌𝚌_𝚟𝚊𝚛 [HoevePesantRousseau04], [HoevePesantRousseau06], [ZanariniMilanoPesant06], 𝚜𝚘𝚏𝚝_𝚛𝚎𝚐𝚞𝚕𝚊𝚛 [HoevePesantRousseau04], 𝚜𝚙𝚛𝚎𝚊𝚍 [PesantRegin05], [SchausDevilleDupontRegin06], 𝚖𝚞𝚕𝚝𝚒𝚌𝚘𝚜𝚝_𝚛𝚎𝚐𝚞𝚕𝚊𝚛 [MenanaDemassey09], 𝚙𝚛𝚎𝚏_𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚟𝚊𝚛 (i.e., variable-based relaxation of 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝 with preferences) [Metivier10], 𝚙𝚛𝚎𝚏_𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚌𝚝𝚛 (i.e., decomposition-based relaxation of 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝 with preferences) [Metivier10], 𝚙𝚛𝚎𝚏_𝚐𝚕𝚘𝚋𝚊𝚕_𝚌𝚊𝚛𝚍𝚒𝚗𝚊𝚕𝚒𝚝𝚢_𝚕𝚘𝚠_𝚞𝚙_𝚟𝚊𝚛 (i.e., variable-based relaxation of 𝚐𝚕𝚘𝚋𝚊𝚕_𝚌𝚊𝚛𝚍𝚒𝚗𝚊𝚕𝚒𝚝𝚢_𝚕𝚘𝚠_𝚞𝚙 with preferences) [Metivier10], 𝚙𝚛𝚎𝚏_𝚐𝚕𝚘𝚋𝚊𝚕_𝚌𝚊𝚛𝚍𝚒𝚗𝚊𝚕𝚒𝚝𝚢_𝚕𝚘𝚠_𝚞𝚙_𝚌𝚝𝚛 (i.e., decomposition-based relaxation of 𝚐𝚕𝚘𝚋𝚊𝚕_𝚌𝚊𝚛𝚍𝚒𝚗𝚊𝚕𝚒𝚝𝚢_𝚕𝚘𝚠_𝚞𝚙 with preferences) [Metivier10]. Finally we only consider a restricted number of constraints involving set variables since this is a relatively new area, which is currently growing rapidly since 2003.
