,Packing Centrosymmetric Patterns of , Nonattacking Queens on an ,×, Board,(.) is the maximum number of patterns that can sit on the .×. board where each pattern consists of . nonattacking Queens placed symmetrically around the center. Each square of the board has at most one Queen. .(.) is the same except that “placed symmetrically around the center” is not required.

A Probabilistic Approach on Estimating the Number of Modular Sonar SequencesWe report some results of an extensive computer search for . ×. modular sonar sequences and estimate the number of inequivalent examples of size . ×. using a probabilistic approach. Evidence indicates strongly that a full size example exists with extremely small probability for large ..

Efficient Algorithms for Sequence AnalysisWe consider new algorithms for the solution of many dynamic programming recurrences for sequence comparison and for RNA secondary structure prediction. The techniques upon which the algorithms are based effectively exploit the physical constraints of the problem to derive more efficient methods for sequence analysis.

Read/Write Isolated MemoryWe find upper and lower bounds on the code rate for a binary, rewritable medium in which adjacent locations may not both store 1’s, and adjacent locations may be not altered during a single rewriting pass. If the true rate is close to our lower bound, then a trivially simple code comes close to optimality.

Binary Perfect Weighted Coverings (PWC)This paper deals with an extension of perfect codes to fractional (or weighted) coverings. We shall derive a Lloyd theorem—a strong necessary condition of existence— and start a classification of these perfect coverings according to their diameter. We illustrate by pointing to list decoding.
