Adaptive simulated annealing for CT image classification
Albrecht, A.; Loomes, M.J.; Steinhofel, K.; Wong, C.K. (2002)We present a pattern classification method that combines the classical Perceptron algorithm with simulated annealing. For a sample set S of n-dimensional patterns labeled as positive and negative, our algorithm computes ... -
Approximation of Boolean Functions by Local Search
Albrecht, A.; Wong, C.K. (2004)Usually, local search methods are considered to be slow. In our paper, we present a simulated annealing-based local search algorithm for the approximation of Boolean functions with a proven time complexity that behaves ... -
Bounded-depth threshold circuits for computer-assisted CT image classification
Albrecht, A.; Hein, E.; Steinhofel, K.; Taupitz, M.; Wong, C.K. (2001)We present a stochastic algorithm that computes threshold circuits designed to discriminate between two classes of computed tomography (CT) images. The algorithm employs a partition of training examples into several classes ... -
Combining the perception algorithm with logarithmic simulated annealing
Albrecht, A.; Wong, C.K. (2001)We present results of computational experiments with an extension of the Perceptron algorithm by a special type of simulated annealing. The simulated annealing procedure employs a logarithmic cooling schedule (-), where ... -
An Experimental Analysis of Local Minima to Improve Neighbourhood Search
Steinhofel, K.; Albrecht, A.; Wong, C.K. (2003)The paper reports the results from a number of experiments on local search algorithms applied to job shop scheduling problems. The main aim was to get insights into the structure of the underlying configuration space. We ... -

Logarithmic simulated annealing for computer-assisted x-ray diagnosis
Albrecht, A.; Steinhofel, K.; Taupitz, M.; Wong, C.K. (2001)We present a new stochastic learning algorithm and first results of computational experiments on fragments of liver CT images. The algorithm is designed to compute a depth-three threshold circuit, where the first layer is ... -
On the convergence of inhomogeneous Markov chains : Approximating equilibrium placements of flexible objects
Albrecht, A.; Cheung, S.K.; Leung, K.S.; Wong, C.K. (2001)This paper deals with the minimization of local forces in two-dimensional placements of flexible objects within rigid boundaries. The objects are disks of the same size but, in general, of different materials. Potential ...
