Branch and Bound for Global NLP: New Bounding LPT G W EpperlyR E SwaneyWe present here a new method for bounding nonlinear programs which forms the foundation for a branch and bound algorithm presented in the next chapter. The bounding method is a generalization of the method proposed by ...
In particular, it was shown by Lai and Sahni [5] that when n 1 < n 2 < 2(n 1 - 1), anomalies may occur in best-bound-first parallel branch-and-bound al- gorithms, even when the bounding function is one-to-one. They suggested that it is quite possible that no anomaly occurs ...
Pruning requires to perform the bounding operation, which consists of applying a lower bound function to the subproblems generated during the exploration process. Preliminary experiments performed on the Flow-Shop scheduling problem (FSP) have shown that the bounding operation consumes over 98 % of ...
It is often slightly smaller in old age. The function of the pupil is to regulate the amount of light admitted into the eye, to optimize the depth of focus and to mitigate ocular aberrations. See acorea; anisocoria; corectopia; dicoria; dyscoria; hippus; iridectomy; microcoria; miosis;...
The scoring of contractions (and simultaneously the selection of inserted points) is done inDecimator::computeEdgeContraction()by minimizing cost functions. A cost function is represented by a matrix, which is computed in theMetricGeneratorclass depending on the settings. ...

They exploit the observation that the appearance of objects changes as a function of viewpoint and that discretization of viewpoints (parametrized by az- imuth and elevation) gives rise to sub-categories which can be trained discriminatively [23]. In more restrictive driving scenarios alternatives ...
Word image spotter 35 preferably includes at least one non-keyword model in addition to the keyword models, and can also be provided with models of function words (prepositions, conjunctions, and articles). FIG. 2B is a flow diagram of a keyword spotting system 50 that uses text line ...
To provide a deeper analysis we finally compare the upper bounds found by the proposed algorithm on the same benchmarks with the best heuristic solutions known in the open literature. Also, in this case, the proposed truncated branch and bound was often able to outperform these heuristic ...
