چکیده

Sequence alignment is an important problem in computational biology. We compare two different approaches to the problem of optimally aligning two or more character strings: bounded dynamic programming (BDP), and divide-and-conquer frontier search (DCFS). The approaches are compared in terms of time and space requirements in 2 through 5 dimensions with sequences of varying similarity and length. While BDP performs better in two and three dimensions, it consumes more time and memory than DCFS for higher-dimensional problems.

An Application of the ABS LX Algorithm to Multiple Sequence Alignment

We present an application of ABS algorithms for multiple sequence alignment (MSA). The Markov decision process (MDP) based model leads to a linear programming problem (LPP), whose solution is linked to a suggested alignment. The important features of our work include the facility of alignment of multiple sequences simultaneously and no limit for the length of the sequences. Our goal here is to ...

A Cuckoo search algorithm (CSA) for Precedence Constrained Sequencing Problem (PCSP)

Precedence constrained sequencing problem (PCSP) is related to locate the optimal sequence with the shortest traveling time among all feasible sequences. In PCSP, precedence relations determine sequence of traveling between any two nodes. Various methods and algorithms for effectively solving the PCSP have been suggested. In this paper we propose a cuckoo search algorithm (CSA) for effectively ...

External Memory Best-First Search for Multiple Sequence Alignment

Multiple sequence alignment (MSA) is a central problem in computational biology. It is well known that MSA can be formulated as a shortest path problem and solved using heuristic search, but the memory requirement of A* makes it impractical for all but the smallest problems. Partial Expansion A* (PEA*) reduces the memory requirement of A* by generating only the most promising successor nodes. H...
