Numerical methods for physics simulations.
... This is essentially the Baraff [1] cloth method when α = 0. In general, the case with α = 1/2 is best as it corresponds to the midpont rule but one must explictly add some damping. The matrix multiplying xn+1 is symmetric but not necessarily positive definite. In addition, the factor of k is problem ...

A virtual element method with arbitrary regularity
... However, for α = 0 and m > 1, even on triangles, the virtual element schemes are no longer conforming finite elements as the internal degrees of freedom are not the same as those used in the higher-order conforming finite element approximation; cf. Beirão da Veiga et al. (2011b) and Beirão da Veiga ...

improving the planning solution quality by replanning
... as those achieved from scratch (Koenig et al, 2002). The adaptation of a plan can be also useful for generative planning systems. The new planning paradigm, called Planning by Rewriting (PbR), uses an adaptation phase, called rewriting, that turns a low quality plan into a high quality plan by using ...

These factorizations provide an efficient way to solve linear systems and least squares problems, but can also be us ...
