WebJan 12, 2024 · We also introduce four different robotic simulation experiments and compare the proposed method to the most common contact solver, the projected Gauss-Seidel (PGS) method. We show that, while both methods are very efficient in solving simple problems, the proposed method significantly outperforms the PGS method in more complicated contact ... http://mft-spirit.nl/files/MTamis_PGS_SI_Comparison.pdf
WebFeb 3, 2024 · The projected Gauss–Seidel (PGS) method is designed to solve more general LCPs in the sense that the assumption for \(\varvec{A}\) is only positive definiteness. The PGS method is an iterative method and generates a sequence \(\left\{ \varvec{\lambda }^k\right\} _{k=0}^{\infty } \subset \mathbb {R}^m\) .

WebWe combine the Projected Gauss–Seidel method with a subspace minimization method. Our new method shows improved qualities and superior convergence properties for specific configurations. Keywords Contact Force Complementarity Problem Linear Complementarity Problem Merit Function Nonlinear Complementarity Problem WebUnmerging relies on an inexpensive single iteration projected Gauss-Seidel sweep over contacts between merged bodies, which lets us update internal contact forces over time, and use the same metrics as merging to identify when bodies should unmerge.
WebSep 23, 2008 · The paper proposes an improvement of a method described by Kocvara and Zowe (Numer Math 68:95–106, 1994) that combines projected Gauss–Seidel iterations with subspace minimization steps. The proposed algorithm employs a recursive subspace minimization designed to handle severely ill-conditioned problems.
WebMay 29, 2010 · According to Wikipedia, the Gauss-Seidel Iteration for solving a linear system of equations Ax=b converges if A is symmetric positive-definite, or A is strictly or irreducibly diagonally dominant.
