Program Schemes, Queues, the Recursive Spectrum and Zero-One Lawstted accepts exactly the class of recursively solvable problems. The class of problems accepted when access to the numeric universe is removed is exactly the class of recursively solvable problems that are closed under extensions. We build upon NSPQ(1) an in?nite hierarchy of classes of program sche

Enhanced Sequence Reconstruction with DNA Microarray Applications the design of the probing scheme and of the associated sequence reconstruction algorithm.Recen tly a novel probing scheme, whose performance is within a constant factor of the information theory bound, has settled the issue of asymptotic optimality.Thus, the research focus has shifted to the ?ne t

Non-approximability of Weighted Multiple Sequence Alignmente .-complete and can be approximated within a constant factor, but it is unknown whether it has a polynomial time approximation scheme. Weighted multiple sequence alignment can be approximated within a factor of .(log..) where . is the number of sequences..We prove that weighted multiple sequence al

A Greedy Algorithm for Optimal Recombinationa recombination of s. and s. at position . is de?ned as an operation that crosses s. and s. at position . and generates t.=a.a....a.b.+1...b. and t.=b.b....b.a.+1... a.. Denote . and . two collections of sequences. In this paper, we discuss generating . from . by a series of recombinations in minimu

Generating Well-Shaped ,-dimensional Delaunay Meshesis well-shaped if the maximum aspect ratio of all its simplices is bounded from above by a constant. It is a long-term open problem to generate well-shaped .-dimensional Delaunay meshes for a given polyhedral domain. In this paper, we present a re?nement-based method that generates well-shaped .-dim
