An efficient algorithm to find certain elements of inverse of a sparse matrixMahfouzi, Farzad
Our second contribution is a matrix-free algorithm to find a minimizer of the regularized reaper which is also suited for high-dimensional data. The algorithm couples a primal-dual minimization approach with a thick-restarted Lanczos process. This appears to be the first efficient convex variational...
In order to solve the inverse kinematics (IK) of complex manipulators efficiently, a hybrid equilibrium optimizer slime mould algorithm (EOSMA) is proposed. Firstly, the concentration update operator of the equilibrium optimizer is used to guide the anisotropic search of the slime mould algorithm to...
Thus, the state transition matrix Fk reduces to a unit matrix I and the system noise wk is not included. The inverse problem such that heat fluxes on the boundary points will be identified from interior measurement data is discussed in this paper. The mathematical model in solving our inverse...
Finding the ground state of a quantum many-body system is a fundamental problem in quantum physics. In this work, we give a classical machine learning (ML) algorithm for predicting ground state properties with an inductive bias encoding geometric localit
their exact solutions. However, matrices with high dimensions (e.g.,A,Bof size) cause their Kronecker product dimension to be very high (, in that case). The dimension problem leads to a computational difficulty due to exceeding computer memory when computing an inverse of the large matrix. ...

The scrambled RGB components were exchanged and mixed randomly under the control of a matrix defined by random angle. DCT was employed to change the pixel values of the color image. In this encryption scheme, the above-mentioned operations were performed twice continuously. The Arnold transform ...
RBDL is a C++ library that contains some essential and efficient rigid body dynamics algorithms such as the Articulated Body Algorithm (ABA) for forward dynamics, Recursive Newton-Euler Algorithm (RNEA) for inverse dynamics, the Composite Rigid Body Algo
The algorithm handles each update in O(mα(m,n)) amortized time, and each query in O(1) time, where α(m,n) is a functional inverse of Ackermann's function appearing in the analysis of the union-find data structure. Note that the update time of O(mα(m,n)), ...
