Item A MAP REDUCE MODEL TO FIND LONGEST COMMON SUBSEQUENCE USING NON-ALIGNMENT BASED APPROACH(Pulchowk Campus, 2016-10) KANDEL, NARAYAN PRASADBiological sequences Longest Common Subsequence (LCS) identification has significant applications in bioinformatics. Due to the emerging growth of bioinformatics applications, new biological sequences with longer length have been used for processing, making it a great challenge for sequential LCS algorithms. Few parallel LCS algorithms have been proposed but their efficiency and effectiveness are not satisfactory with increasing complexity and size of the biological data. An non-alignment based method of sequence comparison using single layer map reduce based scalable parallel algorithm is presented with some optimization for computing LCS between genetic sequences.Item A MapReduce Based Parallel Algorithm for Finding Longest Common Subsequence in Biosequences(Pulchowk Campus, 2014-11) Bohara, JnaneshwarThe Longest Common Subsequence(LCS) identification of biological sequences has significant aplications in bioinformatics. Due to the emerging growth in bioinformatics applications, new biological sequences with longer length have been used for processing, making it great challenge for sequenctial LCS algorithms. Few parallel LCS algorithms have been proposed but their efficiency and effectiveness are not satisfactory with increasing complexity and size of biological data. To overcome limitations of existing LCS algorithms and considering MapReduce programming model as promising technology for cost effective high performace parallel computing, MapReduce based parallel algorithm for LCS has been developed. This algorithm adopts the concepts of successor tables, identical character pairs, successor tree and traversal of successor tree to find Longest Common Subsequence. The hadoop framework is used for the realization of MapReduce model.
