Many realworld optimization problems are dynamic optimization problems (DOPs), where changes may occur over time regarding the objective function, decision variable, and constraints, etc. DOPs raise big challenges to traditional optimization methods as well as evolutionary algorithms (EAs). The last decade has witnessed increasing research efforts on handling dynamic optimization problems using...

We present the first purely semiclassical calculation of the resonance spectrum in the diamagnetic Kepler problem (DKP), a hydrogen atom in a constant magnetic field with Lz = 0. The classical system is unbound and completely chaotic for a scaled energy ∼ EB−2/3 larger than a critical value c > 0. The quantum mechanical resonances can in semiclassical approximation be expressed as the zeros of ...

Many q-differential operators arise in the study of q-special functions, Casimir operators, quantum groups, and representation theory. There are also natural origins via quantum integrable systems and the quantization of classical integrable systems. The latter is often expressed via a q-hierarchy picture akin to the standard Hirota–Lax–Sato formulation and this has many canonical aspects. On t...

Ontology alignment is widely used to €nd the correspondences between di‚erent ontologies in diverse €elds. A‰er discovering the alignment by methods, several performance scores are available to evaluate them. Œe scores require the produced alignment by amethod and the reference alignment containing the underlying actual correspondences of the given ontologies. Œe current trend in alignment eval...

The Accurate calculation of the workspace and joint space for 3 RPS parallel robotic manipulator is a highly addressed research work across the world. Researchers have proposed a variety of methods to calculate these parameters. In the present context a cylindrical algebraic decomposition based method is proposed to model the workspace and joint space. It is a well know feature that this robot ...
