Generating of Test Data by Harmony Search Against Genetic Algorithms

Many search-based algorithms have been successfully applied in sev-eral software engineering activities.Genetic algorithms(GAs)are the most used in the scientific domains by scholars to solve software testing problems.They imi-tate the theory of natural selection and evolution.The harmony search algorithm(HSA)is one of the most recent search algorithms in the last years.It imitates the behavior of a musician tofind the best harmony.Scholars have estimated the simi-larities and the differences between genetic algorithms and the harmony search algorithm in diverse research domains.The test data generation process represents a critical task in software validation.Unfortunately,there is no work comparing the performance of genetic algorithms and the harmony search algorithm in the test data generation process.This paper studies the similarities and the differences between genetic algorithms and the harmony search algorithm based on the ability and speed offinding the required test data.The current research performs an empirical comparison of the HSA and the GAs,and then the significance of the results is estimated using the t-Test.The study investigates the efficiency of the harmony search algorithm and the genetic algorithms according to(1)the time performance,(2)the significance of the generated test data,and(3)the adequacy of the generated test data to satisfy a given testing criterion.The results showed that the harmony search algorithm is significantly faster than the genetic algo-rithms because the t-Test showed that the p-value of the time values is 0.026<α(αis the significance level=0.05 at 95%confidence level).In contrast,there is no significant difference between the two algorithms in generating the adequate test data because the t-Test showed that the p-value of thefitness values is 0.25>α.

In Harmony With Nature

Guyan Huaxiang,literally“ancient weir and picturesque town,”is 20 km away from the centre of Lishui City in Zhejiang Province.It is an idyllic region that features Chinese-style buildings and unblemished natural landscape.The Oujiang River splits the area into two.Guyan,on the north shore,refers to Yantou Village of Bihu Town,which has a 1,000-year-old canal weir and ancient camphor trees.Huaxiang,on the south shore,refers to Dagangtou Town,a beautiful painting town that is home to the vivacious Lishui Barbizon school of painting.

Promoting Human-Nature Harmony

How humans treat nature is of great importance to Earth,the only homeland to all human beings.Should humans endlessly plunder natural resources for material wealth accumulation,just like what the developed Western countries did during their industrialisation,or coexist with nature in harmonious and balanced ways,so as to promote high-quality development,create a high-quality living environment and leave a beautiful homeland featuring blue sky,green land and clean water for the later generations?

Rivers, Terraces, And Timeless Harmony How a natural and a manmade landmark encapsulate some of the core elements of Chinese development philosophy and culture

China’s vast and diverse landscape is a testament to nature’s grandeur,with each region narrating a unique tale of human-nature symbiosis.Among these tales,two landmarks are of profound significance:the Yellow River and the Ziquejie Terraces.These aren’t mere geographical entities;they represent chapters of a story where humans,despite the challenges posed by nature,found ways to coexist,adapt,and thrive.The Yellow River,often dubbed the“Mother River,”has been the cradle of Chinese civilisation,nurturing life and culture for millennia.Similarly,the Ziquejie Terraces,with their intricate patterns,showcase the pinnacle of agricultural innovation and harmony with the land.

How Confucian Philosophy of Balanced Harmony Promotes World Harmony

Harmony is the general principle for dealing with various social problems and promoting world harmony.China regards“harmony is most precious”as its ultimate value goal.Harmony is the core value and moral sentiment of the Chinese nation and it is the criterion for dealing with the relationships between people,between people and society,and between countries.The principles and methods of harmony should be used to govern a state so that it can be in a state of mutual integration.Harmony is a theoretical prescription for solving many crises and contradictions today.It is the meaning and value of learning and understanding universal rule.Harmony is the core value of the Chinese nation,the noumenon and universal rule of human existence,and the well-being of human existence.Harmony has various levels of expression,and its value is mainly reflected in harmony of oneself,harmony of the people,and harmony of nature.Benevolence is the core value concept of balanced harmony,and the philosophy of balanced harmony is realized through propriety.No matter for the communication between individuals,or the relationships between groups,nations,and countries,harmony is the eternal value pursuit and propriety is its eternal value carrier.

Pattern of disharmony between the heart and kidney: Theoretical basis, identification and treatment

'Harmony between the heart and kidney' refers to the physiological relationship between these two zang organs in Chinese medicine,while 'disharmony between the heart and kidney' (also called disharmony between fire and water) refers to the pathological state.The pattern of disharmony between the heart and kidney is widely observed in patients with insomnia,anxiety disorder and menopausal syndrome,etc..In order to gain a full and systematical understanding of this pattern,from the perspective of ancient Chinese philosophy and zang-fu theory in Chinese medicine,we systematically reviewed and discussed the functions and physiological characteristics of the heart and kidney,the origin and development of theories relating to heart-kidney relationship,the pathogenesis and identification of the pattern,as well as the commonly used classical formulas for its treatment,including Coptis and DonkeyHide Gelatin Decoction (Huánglián (E)jiāo Tāng) and Grand Communication Pill (Jiāotài Wán).Two examples of clinical modifications of these formulas in the treatment of insomnia and menopausal syndrome are provided in this article.It should be noted that in clinical practice,these formulas should be used flexibly,and modified in accordance to the condition of the patient.

Harmony Coefficient and Regional Agricultural Systems

The regional agricultural system （RAS） can be divided into three subsystems： ecological, economic, and social. This article examines the use of the harmony coefficient （HC）, efficacy coefficient, rank of the harmony coefficient （RHC）, and its appraising index system within the RAS. The harmony coefficient function was developed using a variance coefficient and then applied to Ziyang District, Yiyang City in Hunan Province （ZYH）, China, as a test case. From 1995 to 2002, the HC of RAS increased from 0.2982 to 0.4826 and the RHC increased from 3 to 5, although the HC trend was an ＂n＂ type in general. This suggests that the HC was weakly maladjusted and the RAS was not harmonious. The HC of the ecological subsystem decreased from 0.3898 to 0.2850, and its RHC from 4 to 3, with the HC trend following the ＂n＂ type. For the economic subsystem, the HC value increased from 0.5767 to 0.7458 and the RHC from 6 to 8. However, the trend in HC for the economic subsystem was of the ＂U＂ type. The HC of the social subsystem increased slightly from 0.4948 to 0.4663, and the RHC did not change in value. From the HC trends, the HC curve of the economic subsystem is above the HC curve of ZYH and the HC curve of the ecological subsystem is below the HC curve of ZHY. Hence, the ZHY environment has been destroyed by economic development. Environment and social building should be regarded as important issues in the future and promoting RAS harmony development should be considered. The results of the theoretical analysis match fairly closely with reality, and suggest that the harmony theory is feasible in appraising RAS development phases.
