Average time complexity analysis of Commentz-Walter algorithm

Commentz-walter: Any Better than Aho- Corasick for Peptide Identification?

An algorithm for locating all occurrences of a finite number of keywords in an arbitrary string, also known as multiple strings matching, is commonly required in information retrieval (such as sequence analysis, evolutionary biological studies, gene/protein identification and network intrusion detection) and text editing applications. Although Aho-Corasick was one of the commonly used exact mul...

Improving average time complexity of Tiling Arrays Using A* Algorithm

Tiling Arrays hybridize labeled target molecules to unlabeled probes fixed on to a solid surface. Tiling arrays vary in the character of the probes. Number of features on a single array can range from 10,000 to greater than 6,000,000, with each feature containing millions of copies of one probe ABSTRACT Genomic tiling arrays are able to inspect the entire genome of random species for which the ...

Average Time Complexity of the SAT 1.2 Algorithm

Time and Space Complexity Reduction of a Cryptanalysis Algorithm

Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...

Average Time Complexity

We extend Levin's theory of average polynomial time to arbitrary time-bounds in accordance with the following general principles: (1) It essentially agrees with Levin's notion when applied to polynomial time-bounds. (2) If a language L belongs to DTIME(T(n)), for some time-bound T (n), then every distributional problem (L;) is T on the-average. (3) If L does not belong to DTIME(T(n)) almost eve...
