# Physical portrayal of computational complexity

@article{Annila2009PhysicalPO, title={Physical portrayal of computational complexity}, author={Arto Annila}, journal={ArXiv}, year={2009}, volume={abs/0906.1084} }

Computational complexity is examined using the principle of increasing entropy. To consider computation as a physical process from an initial instance to the final acceptance is motivated because information requires physical representations and because many natural processes complete in nondeterministic polynomial time (NP). The irreversible process with three or more degrees of freedom is found intractable when, in terms of physics, flows of energy are inseparable from their driving forces…
