Quantum path minimization: An efficient method for global optimization
نویسندگان
چکیده
A new unbiased global optimization approach is proposed, based on quantum staging path integral Monte Carlo sampling and local minimization of individual imaginary time slices. This algorithm uses the quantum tunneling effect to speed up the crossing of energy barriers. This method differs in important ways from previous work on quantum annealing and is able to find all the global minima of Lennard-Jones clusters of size up to N5100, except for N576, 77, and 98. The comparison between this new algorithm and several other classes of algorithms is presented. © 2003 American Institute of Physics. @DOI: 10.1063/1.1527919#

Designing a quantum genetic controller for tracking the path of quantum systems
Based on learning control methods and computational intelligence, control of quantum systems is an attractive field of study in control engineering. What is important is to establish control approach ensuring that the control process converges to achieve a given control objective and at the same time it is simple and clear. In this paper, a learning control method based on genetic quantum contr...
متن کاملEfficient Genetic Based Methods for Optimizing the Reversible and Quantum Logic Circuits
Various synthesis methods have been proposed in the literature for reversible and quantum logic circuits. However, there are few algorithms to optimize an existing circuit with multiple constraints simultaneously. In this paper, some heuristics in genetic algorithms (GA) to optimize a given circuit in terms of quantum cost, number of gates, location of garbage outputs, and delay, are proposed. ...

متن کاملAn efficient one-layer recurrent neural network for solving a class of nonsmooth optimization problems
Constrained optimization problems have a wide range of applications in science, economics, and engineering. In this paper, a neural network model is proposed to solve a class of nonsmooth constrained optimization problems with a nonsmooth convex objective function subject to nonlinear inequality and affine equality constraints. It is a one-layer non-penalty recurrent neural network based on the...
متن کاملEfficient uncertainty minimization for spectral macrostate data clustering
Spectral clustering, which uses the global information embedded in eigenvectors of an interitem relationship matrix, can outperform traditional approaches such as k-means and hierarchical clustering. Spectral hierarchical bipartitioning is well-understood, but spectral multipartitioning remains an interesting research topic. Korenblum and Shalloway [Phys. Rev. E 67, 056704 (2003)] used an analo...
