SqFreeEVAL: An (almost) optimal real-root isolation algorithm
Let f be a univariate polynomial with real coefficients, f ∈ R[X]. Subdivision algorithms based on algebraic techniques (e.g., Sturm or Descartes methods) are widely used for is...

An Adaptive Technique for Constructing Robust and High-Throughput Shared Objects
Abstract. Shared counters are the key to solving a variety of coordination problems on multiprocessor machines, such as barrier synchronization and index distribution. It is desire...

Gradient-Based Methods for Sparse Recovery
The convergence rate is analyzed for the sparse reconstruction by separable approximation (SpaRSA) algorithm for minimizing a sum f(x) + ψ(x), where f is smooth and ψ is convex, ...

Robust adaptive beamforming based on jointly estimating covariance matrix and steering vector
In this paper, a new adaptive beamforming algorithm with joint robustness against covariance matrix uncertainty as well as steering vector mismatch is proposed. First, the theoret...
