The NP-complete is a class of complexity including many real-world problems. Although many efforts made to find efficient solutions to NP-complete problems, no such a solution having polynomial complexity of used resources is found yet. Optical computing, as a branch of unconventional computing, provides new capabilities to solve NP-complete problems, using physical properties of light such...
In this paper, an optical wavelength-based method to solve a well-known NP-complete problem 3-SAT is provided. In the 3-SAT problem, a formula F in the form of conjunction of some clauses over Boolean variables is given and the question is to find if F is satisfiable or not. The provided method uses exponential number of different wavelengths in a light ray and considers each group of wavelengths...
