Consider a user searching for information on the World Wide Web. If the information need of the user is somewhat specific, and if the user is permitted to provide a detailed description of his precise need, then it is quite likely that this description will include negative constraints, i.e., specifications of what the user is 'not' looking for. A search engine that makes use of such constraints is...
An approach to include elastic and inelastic electron-phonon scattering into the nonequilibrium Green's function (NEGF) framework that is computationally manageable and applicable to planar MOSFETs has been developed. By reformulating the NEGF equations in terms of integrated transverse momentum modes, the computational burden has been significantly reduced. This allows treatment of both quantum mechanics...
Most optimization problems have constraints of different types (e.g., physical, time, geometric, etc.), which modify the shape of the search space. We propose an ecologically inspired invasive weed optimization (IWO) algorithm to solve the constrained real-parameter optimization problems. Central to our approach is a parameter-free penalty function that we introduce. The adaptive nature of the penalty...
