Optimization of a Classical Algorithm for the Alignment of Genomic Sequences with Artificial Bee Colony

Journal of Mechanics Engineering and Automation 2022年第2期12卷 57-63页

This article shows genomic alignment methods using the classic“Needleman”and“Smith-Waterman”algorithms,the latter they were optimized by the ABC(artificial bee colony)*** the genomic alignment,a goal state is not presented,the experiments that are carried out show alternative alignments by ABC were *** types of alignments could exist within the classical algorithm,based on a horizontal,vertical,diagonal and inverse search mechanism on a match value *** ABC-Smith Waterman algorithm was generated from the genomic sequences written in rows and columns for the search for similarities that will provide values that ABC uses to process and provide more results of alignments that can be used by scientists for their experiments and research.

Background:GPS/GSM tracking data were used to contrast use of(i)habitats and(ii)protected areas between three Arctic-nesting Greater White-fronted Geese(Anser albifrons,GWFG)populations throughout the annual *** wished to demonstrate that the East Asian Continental Population(which winters on natural wetlands in the Chinese Yangtze River floodplain and is currently declining)avoids using farmland at multiple wintering *** also gath-ered tracking evidence to support general observations from two increasing population of GWFG,the North Sea-Baltic(which winters in Europe)and the West Pacific(which winter in Korea and Japan)winter mostly within farmland landscapes,using wetlands only for safe night ***:We tracked 156 GWFG throughout their annual cycle using GPS/GSM transmitters from these three popu-lations to determine migration routes and stopover staging *** used Brownian Bridge Movement Models to generate summer,winter and migration stopover home ranges which we then overlaid in GIS with land cover and protected area boundary at national level to determine habitat use and degree of protection from nature conserva-tion designated ***:Data confirmed that 73%of European wintering GWFG homes ranges were from within farmland,com-pared to 59%in Japan and Korea,but just 5%in China,confirming the heavy winter use of agricultural landscapes by GWFG away from China,and avoidance of farmland at multiple sites within the Yangtze River *** same GWFG used farmland in northeast China in spring and autumn,confirming their experience of exploiting such habi-tats at other stages of their annual *** wintering birds showed the greatest overlap with protected areas of all three populations,showing current levels of site safeguard are failing to protect this ***:Results confirm the need for strategic planning to protect the East Asian Continental GWFG *** the site protection network in place to p
