On a New Method for Derivative Free Optimization
A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ...
Programming with Explicit Dependencies. A Framework for Portable Parallel Programming
Computational devices are rapidly evolving into massively parallel systems. Multicore processors are already standard; high performance processors such as the Cell/BE processor, graphics processing units (GPUs) ...
Structure of Polynomial-Time Approximation
Approximation schemes are commonly classified as being either a polynomial-time approximation scheme (ptas) or a fully polynomial-time approximation scheme (fptas). To properly differentiate between approximation schemes ...
