The translocation operation is one of the popular operations for genome rearrangement. In this paper, we present a 1.75-approximation algorithm for computing unsigned translocation distance which improves upon the best known 2-approximation algorithm [J. Kececioglu, R. Ravi, Of mice and men: Algorithms for evolutionary distances between genomes with translocation, in: 6th ACM-SIAM Symposium on Discrete Algorithms, 1995, pp. 604-613]. © 2007 Elsevier Inc.
