Quality of the design of nucleic acid logic gates using the single-state and multi-state sequence designers. Quality of the design of nucleic acid logic gates using the single-state and multi-state sequence designers. The graphs show the percentage of candidates that passed the filter for every stage in the filter described in Table 4. A Solid line represents candidates that were generated by multi-state designer, and a dashed line represents candidates from the single-state designer. The title of each graph represents from left to right, the output bits of the following input patterns (11, 10, 01, 00), with the inputs in the order of [input-B input-A], see Table 2. For instance, an OR gate is denoted as 1110 in the figure. Refer Tables 8 and 9 for the actual number of candidates.
