TDOA-Based Source Collaborative Localization via Semidefinite Relaxation in Sensor Networks
International Journal of Distributed Sensor Networks, 2015 The time delay of arrival- (TDOA-) based source localization using a wireless sensor network has been considered in this paper. The maximum likelihood estimate (MLE) is formulated by taking the correlated TDOA noise into account, which is caused by the ...

CHARACTERISING SOLUTION SET OF A NONCONVEX PROGRAMMING PROBLEM VIA ITS DUAL PROBLEMS
Tạp chí Khoa học Đại học Đà Lạt, 2012 Using duality theory, we propose a new approach to characterise solution set of a nonconvex optimisation problem. Several characterisations of solution set of the problem are established via it s dual problems.

Technical Note—Sharper Bounds on Nonconvex Programs [PDF]
Operations Research, 1974 Recently it was pointed out that the generalized Lagrange-multiplier method provides a sharper bound on a nonconvex program than does the solution of the program formed by taking convex envelopes of all functions involved in the original problem. This note points out that the bounds are the same if the original problem has only linear constraints, or ...
