The ISCB held its 13th annual Intelligent Systems for Molecular Biology Conference (ISMB) in Detroit, Michigan, June 25– 29, 2005. Considering this conference has moved to many points on the globe in its 13 years, this location was not so far away geographically from the first ISMB held in Bethesda, Maryland, in 1993, but the increase in numbers in all categories—attendance, presentations, and ...

The spectral bundle method was introduced by Helmberg and Rendl [13] to solve a class of eigenvalue optimization problems that is equivalent to the class of semidefinite programs with the constant trace property. We investigate the feasibility and effectiveness of including full or partial second-order information in the spectral bundle method, building on work of Overton and Womersley [20, 23]...

That intravitam staining with basic dyes occurs more readily in alkaline than in acid solutions has long been known. Among the explanations which have been offered to account for this fact two deserve especial mention. The first is that originally proposed byOverton (1), accepted by Harvey (2), and supported in certain respects by the experiments of Robertson (3) (who, however, on other grounds...

In this paper, we first note that Method III in Friedland, Nocedal, and Overton [SIAM J. Numer. Anal., 24 (1987), pp. 634–667] may not converge quadratically in the quotient sense. Then, we show that the method is convergent quadratically under a weaker notion of convergence — the root convergence. We also extend our results to the algorithm given in Chu [SIAM J. Numer. Anal., 29 (1992), pp. 88...

in this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $nondeterministic$ $fuzzy$$finite$ $tree$ $automata$ (nffta). initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). inorder to eliminate these limitations and increasing theefficiency of ffta, we defin...
