The paper reviews the solvability resp. unsolvability of decision problems for the relations represented by deterministic and nondeterministic multi-tape automata with or without endmarker on the one hand and the solvability resp. unsolvability of decision problems for the languages defined by the same types of automata on the other hand. The first section presents results on the inclusions between the different classes of relations and languages under consideration. The second section deals with decision problems for relations. The main new result here is that all the considered problems are decidable for autonomous relations. The last section contains the results on the solvability resp. unsolvability of decision problems for languages. These results are sharpenings of known ones, some of them are entirely new.
