In this process, the musicians\n\t\t\t improvise their instrument pitches searching for the perfect state of harmony. \n\t\t\t Practical experiences, however, suggest that the algorithm suffers from the\n\t\t\t problems of slow and\/or premature convergence over multimodal and rough fitness\n\t\t\t landscapes. This paper presents an attempt to improve the search performance of\n\t\t\t HS by hybridizing it with Differential Evolution (DE) algorithm. The\n\t\t\t performance of the resulting hybrid algorithm has been compared with classical\n\t\t\t HS, the global best HS, and a very popular variant of DE over a test-suite of\n\t\t\t six well known benchmark functions and one interesting practical optimization\n\t\t\t problem. The comparison is based on the following performance indices - (i)\n\t\t\t accuracy of final result, (ii) computational speed, and (iii) frequency of\n\t\t\t hitting the optima.<\/jats:p>","DOI":"10.3233\/fi-2009-157","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T22:56:42Z","timestamp":1575327402000},"page":"401-426","source":"Crossref","is-referenced-by-count":113,"title":["An Improved Harmony Search Algorithm with Differential Mutation\t\t\t Operator"],"prefix":"10.1177","volume":"95","author":[{"given":"Prithwish","family":"Chakraborty,","sequence":"first","affiliation":[{"name":"Department of Electronics and Telecommunication\r\t\t\t Engineering, Jadavpur University, Kolkata, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gourab Ghosh","family":"Roy","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunication\r\t\t\t Engineering, Jadavpur University, Kolkata, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Swagatam","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunication\r\t\t\t Engineering, Jadavpur University, Kolkata, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dhaval","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunication\r\t\t\t Engineering, Jadavpur University, Kolkata, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ajith","family":"Abraham","sequence":"additional","affiliation":[{"name":"Machine Intelligence Research Labs (MIR Labs),\r\t\t\t Scientific Network for Innovation and Research Excellence, P.O.
