| Summary: | Unconventional computing plays an important role in computational complexity theory, providing unconventional computing paradigms to tighten the gap between tractable and presumable intractable problems; however, most unconventional paradigms reach similar gaps and their perspective may become stagnant. In this work, we develop a new outlook by a young natural computing paradigm called virus machines (VMs) which takes inspiration from the biological virus life cycle. A new computational complexity theory through VM is developed by attacking a classical NP-complete problem, the Subset Sum problem. It has been uniformly solved by means of deterministic VM. The uniform construction consists of three different modules: one module B for selecting the possible subset; another module $$Y_j$$ Y j that encodes the selection, adds it or not to the final sum, and compares the result; and one last module END to reach the halting configuration and make the output consistent. This design provides a new perspective for solving presumably hard problems by means of families of VMs, opening new research lines in this framework. |
