Simplifying triangulations
We give a new algorithm to simplify a given triangulation with respect to a given curve. The simplification uses flips together with powers of Dehn twists in order to complete in polynomial time in the bit-size of the curve. keywords. triangulations of surfaces, flip graphs, Dehn twists Mathematics Subject Classification (2010): 57M20
متن کاملSimplifying CRISPR
eveloping cell lines for use as accurate models for disease has always been a challenging task. In order to replicate phenotypes or enable downstream experimentation, genome engineering of cell lines is required. Techniques enabling genome modification have evolved over a number of years, from simple viral vectors used to insert sequences in random locations, to more sophisticated methods that ...
متن کاملSimplifying Parallel List Traversal Simplifying Parallel List Traversal
Computations described using Bird's constructive algebra of lists are nicely amenable to parallel implementation. Indeed , by using higher-order functions, ordered list traversals such as foldl and foldr can be expressed as unordered reductions. Based on this observation, a set of optimizations have been developed for list traversals in the parallel Haskell (pH) compilerr12]. These optimization...
متن کاملIntroduction to Motherhood
It is unfortunate that Roddis presents Lind as a personage and tells us so little of the person, or rather of the personality, with the drives and motivations which made for such a wide spectrum of researches and activities. But despite the rather too academic and impersonal handling, the story of James Lind offers interesting and profitable reading.
