我们设计了一个分子图灵机,并确定了分子计算机可解决问题的复杂性。[94]中提出并实现了一种解决哈密顿路径np完全问题的组合分子实验。使用我们的设计,我们表明,在A94中隐含的慷慨假设下,这种分子计算机实际上可以计算PSPACE。在A94]无法满足的更强、更实际的限制条件下,我们证明了分子计算机仅限于解决P中的问题。
We design a molecular Turing machine and determine the complexity of the problems solvable by molecular computers. In A94], a combinatorial molecular experiment to solve the NP-complete problem of Hamiltonian Path was proposed and implemented. Using our design, we show that such molecular computers can in fact compute PSPACE, under the generous assumptions implicit in A94]. Under stronger and somewhat more practical restrictions, which A94] fails to satisfy, we show that molecular computers are limited to solving problems in P.
