The video shows a DNC successfully performing a reasoning problem in a blocks world. A sequence of letter-labeled goals (S, K, R, Q, E) is presented to the network one step at a time. Each goal consists of a sequence of defining constraints, presented one constraint per time-step. For example, S is: 6 below 2 (6b2); 2 right of 5 (2r5); 6 right of 1 (6r1); 5 above 1 (5a1). On the right, the write head edits the memory, writing information about the goals down. Ultimately, the DNC is commanded to satisfy goal “Q”, which it does subsequently by using the read heads to inspect the locations containing goal Q. The constraints constituting goal “Q” are shown below, and the final board position is correct.
