Abstract

© Springer-Verlag Berlin Heidelberg 1994. A scoring scheme is presented to measure the similarity score between two biological sequences, where matches are weighted dependent on their context. The scheme generalizes a widely used scoring scheme. A dynamic programming algorithm is developed to compute a largest-scoring alignment of two sequences of lengths m and n in O(ran) time and O(m+n) space. Also developed is an algorithm for computing a largest-scoring local alignment between two sequences in quadratic time and linear space. Both algorithms are implemented as portable C programs. An experiment is conducted to compare protein alingments produced by the new global alignment program with ones by an existing program.
