FIELD: computer engineering; computing of various options. SUBSTANCE: first circuit is set up of flip-flops 4, 5, 8, 11. Second circuit has flip-flops 12, 13,16,19. Third one incorporates flip-flops 21, 22, 23, 26. Fourth circuit has flip-flops 27, 28, 29, 31. Voltages picked off resistors 30, 49, 58, 67 of conducting flip-flops 4, 13, 23, 31 are applied to base of transistor switch 3. First pulse coming from generator 1 drives flip-flops 5, 16, 26, 27 in conduction. Second pulse drives flip-flops 8, 19, 21, 28 in conduction. Sixth pulse enables flip-flops 8, 19, 22, 27. In this way, flip-flops change their state in different sequence. Conducting flip-flops correspond to departments and sums of money to be placed in them so as to obtain maximal profit. Proposed device enables computation of all options, selection of best one, and attainment of maximal profit. Switching device that has flip-flop circuits of quantity equal to number of flip-flops in single circuit in which output of preceding flip-flop is connected to input of next one and output of last flip-flop is connected to input of first one is characterized in that flip-flops whose serial number corresponds to circuit number and higher up to the last flip-flop are connected to next ones and to first flip-flops through switches coupled with additional flip-flops. EFFECT: improved design. |
