Boosting search by rare events
Random search algorithm combination nonequilibrium random random algorithm
2015/8/21
Randomized search algorithms for hard combinatorial problems exhibit a large variability of per- formances. We study the different types of rare events which occur in such out-of-equilibrium stochasti...
Correlations between Google search data and Mortality Rates
Correlations；Google search data Mortality Rates
2012/11/22
Inspired by correlations recently discovered between Google search data and financial markets, we show correlations between Google search data mortality rates. Words with negative connotations may pro...
A Nonlinear Conjugate Gradient Algorithm with An Optimal Property and An Improved Wolfe Line Search
conjugate gradient method memoryless BFGS method unconstrained optimization global convergence Wolfe line search
2012/8/10
In this paper, we seek the conjugate gradient direction closest to the direction of the
scaled memoryless BFGS method and propose a family of conjugate gradient methods for
unconstrained optimizatio...
Stochastic Service Systems, Random Interval Graphs and Search Algorithms
Queueing theory interval graphs Lambert series asymptotic expansions
2011/9/15
Abstract: We consider several stochastic service systems, and study the asymptotic behavior of the moments of various quantities that have application to models for random interval graphs and algorith...
Search for conformal invariance incompressible two-dimensional turbulence
two-dimensional turbulence conformal invarianc incompressible SLE
2011/7/5
We present a search for conformal invariance in vorticity isolines of two-dimensional compressible
turbulence. The vorticity is measured by tracking the motion of particles that float at the surface ...
A* Orthogonal Matching Pursuit: Best-First Search for Compressed Sensing Signal Recovery
compressed sensing best-first search A* search matching pursuit sparse representations sparse signal
2010/11/29
Compressed sensing is a recently developing area which is interested in reconstruction of sparse signals acquired in reduced dimensions. Acquiring the data with a small number of samples makes the rec...
A program to search for homotopy 3-spheres。
A state space search algorithm and its application to learn the short-term foreign exchange rates
State space search discrete recurrent neural networks absolutelystable foreign exchange rates
2010/9/13
We propose the use of a state space search algorithm of the discretetime recurrent neural network to learn the short-term foreign exchange rates. By searching in the neighborhood of the target traject...
AN SQP ALGORITHM WITH NONMONOTONE LINE SEARCH FOR GENERAL NONLINEARCONSTRAINED OPTIMIZATION PROBLEM
2007/12/11
In this paper, an SQP type algorithm with a new nonmonotone line search
technique for general constrained optimization problems is presented.
The new algorithm does not have to solve the second orde...
The Global Convergence of Self-scale BFGS Algorithm with Nonmonotone Line Search for Unconstrained Nonconvex Optimization Problems
nonmonotone line search self-scaling BFGS method global convergence
2007/12/11
The self-scaling quasi-Newton method solves an unconstrained optimization problem by scaling the Hessian approximation matrix before it is updated at each iteration to avoid the possible large eigenva...
