A pivoting strategy for symmetric tridiagonal matrices
The LBL factorization of Bunch for solving linear systems involving a symmetric indefinite tridiagonal matrix T is a stable, efficient method. It computes a unit lower triangular matrix L and a block 1×1 and 2×2 matrix B such that T = LBL . Choosing the pivot size requires knowing a priori the largest element σ of T in magnitude. In some applications, it is required to factor T as it is formed ...
متن کاملA Pivoting Gripper for Feeding Industrial Parts
To be cost effective and highly precise, many industrial assembly robots have only four degrees of freedom (D.O.F. ) plus a binary pneumatic gripper. Such robots commonly permit parts to be rotated only about a vertical axis. However it is often necessary to reorient parts about other axes prior to assembly. In this paper we describe a way to orient parts about an arbitrary axis by introducing ...
متن کاملReinforcement Learning for Pivoting Task
In this work we propose an approach to learn a robust policy for solving the pivoting task. Recently, several model-free continuous control algorithms were shown to learn successful policies without prior knowledge of the dynamics of the task. However, obtaining successful policies required thousands to millions of training episodes, limiting the applicability of these approaches to real hardwa...
متن کاملA generalized complementary pivoting algorithm
The first algorithm to use a complementary pivoting procedure was that devised by Lemke and Howson to find a Nash equilibrium point of a bimatrix game [ 15 ]. This algorithm introduced a novel proof of convergence not relying on standard monotonicity arguments. Lemke [ 12] generalized his complementary pivot algorithm to solve certain classes of linear complementarity problem (LCP), which Dantz...
متن کاملStability of the Diagonal Pivoting Method with Partial Pivoting
LAPACK and LINPACK both solve symmetric indefinite linear systems using the diagonal pivoting method with the partial pivoting strategy of Bunch and Kaufman [Math. Comp., 31 (1977), pp. 163–179]. No proof of the stability of this method has appeared in the literature. It is tempting to argue that the diagonal pivoting method is stable for a given pivoting strategy if the growth factor is small....
