Optimizing Gershgorin for symmetric matrices [PDF]
Linear Algebra and its Applications, 2019 The Gershgorin Circle Theorem is a well-known and efficient method for bounding the eigenvalues of a matrix in terms of its entries. If $A$ is a symmetric matrix, by writing $A = B + x{\bf 1}$, where ${\bf 1}$ is the matrix with unit entries, we consider the problem of choosing $x$ to give the optimal Gershgorin bound on the eigenvalues of $B$, which ...

Numerical optimization for symmetric tensor decomposition [PDF]
Mathematical Programming, 2015 We consider the problem of decomposing a real-valued symmetric tensor as the sum of outer products of real-valued vectors. Algebraic methods exist for computing complex-valued decompositions of symmetric tensors, but here we focus on real-valued decompositions, both unconstrained and nonnegative, for problems with low-rank structure.

The Optimum Design of Scanned Linear Antenna Array Using Sine Cosine Optimization Algorithm
Wasit Journal of Computer and Mathematics Science, 2023 In this article, the side lobe level (SLL) of the radiation pattern is reduced, and the first null beam width (FNBW) is kept constant by synthesizing symmetric scanning Linear Antenna Arrays (LAA), which is done by considering excitation amplitude as ...

The optimal prize structure of symmetric Tullock contests [PDF]
Public Choice, 2009 We show that the optimal prize structure of symmetric n-player Tullock tournaments assigns the entire prize pool to the winner, provided that a symmetric pure strategy equilibrium exists. If such an equilibrium fails to exist under the winner-take-all structure, we construct the optimal prize structure which improves existence conditions by dampening ...

Symmetric tensor networks for generative modeling and constrained combinatorial optimization
Machine Learning: Science and Technology, 2023 Constrained combinatorial optimization problems abound in industry, from portfolio optimization to logistics. One of the major roadblocks in solving these problems is the presence of non-trivial hard constraints which limit the valid search space.
