Approximate Clustering of Fingerprint Vectors with Missing Values

Figueroa, A., Goldstein, A., Jiang, T., Kurowski, M., Lingas, A. and Persson, M.

    We study the problem of clustering fingerprints with at most p missing values (CMV(p) for short) naturally arising in oligonucleotide fingerprinting, which is an efficient method for characterizing DNA clone libraries. We show that already CMV(2) is NP-hard. We also show that a greedy algorithm yields a min(1 + ln n; 2+p ln l) approximation for CMV(p), and can be implemented to run in O(nl2p) time. Furthermore, we introduce other variants of the problem of clustering fingerprints with at most p missing values based on slightly different optimization criteria and show that they can be approximated in polynomial time with ratios 22p
