The Most Likely Optimal Symmetric RVLC
IEEE Transactions on Communications, 2015For each alphabet size up to 30, a symmetric reversible variable length code (RVLC) is determined which is most likely to be optimal in average codeword length. It is shown that these codes are optimal for more than half of all the possible sources.

Globally Optimal Grouping for Symmetric Boundaries
2006 IEEE Computer Society Conference on Computer Vision and Pattern Recognition - Volume 1 (CVPR'06), 2006Many natural and man-made structures have a boundary that shows certain level of bilateral symmetry, a property that has been used to solve many computer-vision tasks. In this paper, we present a new grouping method for detecting closed boundaries with symmetry.

Optimal trajectories for symmetric turns
American Journal of Physics, 2023The problem of determining minimal time trajectories in a plane constrained by an upper bound on the magnitude of the acceleration vector is reexamined. In the previous work [Am. J. Phys. 49(7), 685–688 (1981)], a stationary solution of a functional, applied over curves in two-dimensional velocity space, was used to find explicit expressions for what ...

Depth Optimized Synthesis of Symmetric Boolean Functions
2021 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2021Symmetric Boolean functions are characterized by the fact that their output can be determined by the Hamming weight of their inputs. Symmetric Boolean functions are essential for many complex systems and possess significant cryptographic properties.Due to their popularity and significance, research has been focusing on optimization of synthesis ...

Second Derivatives for Optimizing Eigenvalues of Symmetric Matrices
SIAM Journal on Matrix Analysis and Applications, 1995Let \(A\) be a twice Lipschitz-continuously differentiable mapping from \(\mathbb{R}^m\) to the set of \(n \times n\) real symmetric matrices. A proof is given of the local quadratic convergence (previously observed numerically) of an iterative method of the first author [SIAM J. Matrix Anal. Appl.

Optimal circularly symmetric quantizers
Journal of the Franklin Institute, 1982Abstract Polar coordinates quantization of the bivariate Gaussian and other cir- cularly symmetric sources has already been investigated. The schemes quantize the polar coordinates representation of the random variables independently in an attempt to reduce the mean square error below that of an analogous rectangular coordinates quantizer.

An Optimal Agorithm for Symbolic Factorization of Symmetric Matrices
SIAM Journal on Computing, 1980A fundamental problem in the computer solution of a sparse, N by N, positive definite system of equations $Ax = b$ is, given the structure of A, to determine the structure of its Cholesky factor L, where $A = LL^T $. This problem arises because it is often desirable to set up a data structure for L before the numerical computation is performed, and in ...
