Many real-world problems are dynamic, requiring an optimization algorithm which is able to continuously track a changing optimum over time. In this paper, we present new variants of Particle Swarm Optimization (PSO) specifically designed to work well in dynamic environments. The main idea is to extend the single population PSO and Charged Particle Swarm Optimization (CPSO) methods by constructi...

Recent research in multi-valued logic for quantum computing has shown practical advantages for scaling up a quantum computer. [1,12] Multivalued quantum systems have also been used in the framework of quantum cryptography, [4] and the concept of a qudit cluster state has been proposed by generalizing the qubit cluster state. [5] An evolutionary algorithm based synthesizer for ternary quantum ci...

Nesvizhevsky et al.[1] performed an experiment to study the problem of gravitational quantum well. The “well” in which a quantum particle (neutron was used in the experiment) bounces back and forth, was formed by placing a horizontal reflecting mirror in the Earth’s gravitational field. The experimental results were in reasonable agreement with the theoretical results. So if there is any noncom...

The propagation of nonlinear quantum dust ion-acoustic (QDIA) solitary waves in a unmagnetized quantum plasma whose constituents are inertialess quantum electrons and  positrons, classical cold ions and stationary negative dust grains are studied by deriving  the Korteweg–de Vries (KdV) equation under the reductive perturbation method. Quantum Hydrodynamic (QHD) equations are used to take into ...
