Recently, a popular metaheuristic algorithm called Harmony Search, conceptualized using the musical process of searching for a perfect state of harmony is undergoing faster developments. In this paper, a new variant of harmony search called Dynamic Hybrid Harmony Search algorithm (DHHS) is proposed. The novelty introduced in this algorithm is the division of the whole population into few sets o...

The CORBA standard, together with its service specifications, has gained considerable attention in recent years. The CORBA Object Query Service allows for declarative access to heterogeneous storage systems. We have come up with an implementation of this service called Harmony. The objective of this article is to provide a detailed description and quantitative assessment of Harmony. Its main te...

This paper presents a kernel fuzzy clustering with a novel differential harmony search algorithm to coordinate with the diversion scheduling scheme classification. First, we employed a self-adaptive solution generation strategy and differential evolution-based population update strategy to improve the classical harmony search. Second, we applied the differential harmony search algorithm to the ...

Harmony is a concept that plays a pivotal role throughout Chinese history (Li, 2008 ) as much as love does in Christianity. Also similar to love in Christianity, much good as well as evil has been done in the name of harmony. It is important therefore to delineate the basic structure of this root metaphor in order to differentiate between optimal and suboptimal versions of harmony. This chapter...

This paper presents experimentally based rules and methods for the creation of harmonic color sets. First, dichromatic rules are presented which concern the harmony relationships of two hues. For an arbitrarily given hue pair, we define the just harmonic saturation values, resulting in minimally harmonic color pairs. These values express the fuzzy border between harmony and disharmony regions u...

Tahltan is an Athapaskan language with perhaps the world's only three-way consonant harmony system (dental, alveolar, and alveopalatal). Although most explanations have depended on feature analysis, Gafos [1] proposed that differences in tongue grooving could account for the pattern. Here, we use ultrasound to examine the initial plausibility of this argument by determining whether a language w...

Derivational sequences and harmony scales are collections of relationships between phonological structures that are used to pick out a grammatical surface representation: a surface representation is the final form in a sequence in derivational phonology; it is the optimal form on a scale of relative harmony in optimality phonology. The two approaches would match still further if traversing alon...

Combinations of metaheuristics to solve highly constrained combinatorial optimisation problems have recently become a promising research area. Some combinations emerge from integrating evolutionary algorithms and local based algorithms to strike the right balance between global exploration of the search region and local exploitation of promising regions. This study presents hybridization betwee...

This study investigates the distortion of visual colour harmony impression in case of different types of artificial changes among the perceptual attributes of test samples. A set of visual experiments were carried out to investigate the observer’s colour harmony impression as a function of artificial distortions. The visual colour harmony impression of a colour combination appearing harmonious ...
