Distribution System State Estimation: A Semidefinite Programming Approach

IEEE Transactions on Smart Grid, 2019
Distribution system state estimation (DSSE) is one of the vital components in the next-generation distribution management system which allows operators to monitor the entire system’s operating conditions.

Semidefinite Programming for NLOS Error Mitigation in TDOA Localization

IEEE Communications Letters, 2018
Non-line-of-sight (NLOS) error mitigation for the time-of-arrival (TOA) localization has been extensively studied, but these methods cannot be directly applied for the time-difference-of-arrival (TDOA) systems. Recent work has applied convex optimization

Bounds on mean energy in the Kuramoto–Sivashinsky equation computed using semidefinite programming

Nonlinearity, 2018
We present methods for bounding infinite-time averages in dynamical systems governed by nonlinear PDEs. The methods rely on auxiliary functionals, which are similar to Lyapunov functionals but satisfy different inequalities. The inequalities are enforced

Accurate Localization of Multiple Sources Using Semidefinite Programming Based on Incomplete Range Matrix

IEEE Sensors Journal, 2016
We address the problem of locating multiple sources from the Euclidean distance matrix (EDM), which can be obtained from the received signal strength or time of arrival measurements.

Semidefinite Programming Problems

1999
Semidefinite programming involves the minimization of a linear function subject to the constraint that an affine combination of symmetric matrices is positive semidefinite. Several types of problems can be transformed to this form. This constraint is in general nonlinear and nonsmooth yet convex.

Improving the Semidefinite Programming Bound for the Kissing Number by Exploiting Polynomial Symmetry

Experimental Mathematics, 2016
The kissing number of $\mathbb{R}^n$ is the maximum number of pairwise-nonoverlapping unit spheres that can simultaneously touch a central unit sphere. Mittelmann and Vallentin (2010), based on the semidefinite programming bound of Bachoc and Vallentin ...

Semidefinite programming and combinatorial optimization

Mathematical Programming, 1997
We discuss the use of semidefinite programming for combinatorial optimization problems. The main topics covered include (i) the Lovász theta function and its applications to stable sets, perfect graphs, and coding theory, (ii) the automatic generation of strong valid inequalities, (iii) the maximum cut problem and related problems, and (iv) the ...
