Webcomplexity (1.1). Both results utilize the fast determinant algorithm for matrix polynomials (Storjohann 2002, 2003). The algorithm by Kaltofen (1992) (see case ii above) was originally put to a di erent use, namely that of computing the characteristic polynomial and adjoint of a matrix without divisions, counting additions, subtractions, and WebA new effective algorithm for handling of geometry at chiral centers for the processing of stereochemical structures during their unambiguous registration in databases was designed, programmed and implemented. The chemical and mathematical reasoning behind the algorithm are discussed in detail. Its advantages- in comparison to the methods used so …
