Stopping rules for box-constrained stochastic global optimization
We present three new stopping rules for Multistart based methods. The first uses a device that enables the determination of the coverage of the bounded search domain. The second i...

Determination of Optimal Distortion-Based Protection in Progressive Image Transmission: a Heuristic Approach
— In this paper a method for the fast determination of distortion-based optimal unequal error protection (UEP) of bitstreams generated by embedded image coders is described. The ...
