One of the main concerns of the mining industry is to determine ultimate pit limits. Final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. The size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...

Stochastic nature of earthquake has raised a challenge for engineers to choose which record for their analyses. Clustering is offered as a solution for such a data mining problem to automatically distinguish between ground motion records based on similarities in the corresponding seismic attributes. The present work formulates an optimization problem to seek for the best clustering measures. In...

For any p ∈ [0, 2], we give a 1-pass poly(ε−1 logn)-space algorithm which, given a data stream of length m with insertions and deletions of an n-dimensional vector a, with updates in the range {−M,−M +1, · · · ,M −1,M}, outputs a sample of [n] = {1, 2, · · · , n} for which for all i the probability that i is returned is (1 ± ) |ai| p Fp(a) ± n−C , where ai denotes the (possibly negative) value ...

We study the computation complexity of Boolean functions in the quantum black box model. In this model our task is to compute a function f : {0, 1} → {0, 1} on an input x ∈ {0, 1} that can be accessed by querying the black box. Quantum algorithms are inherently probabilistic; we are interested in the lowest possible probability that the algorithm outputs incorrect answer (the error probability)...

In practical applications evaluating a fitness function is frequently subject to noise, i. e., the “true fitness” is disturbed by some random variations. Evolutionary algorithms (EAs) are often successfully applied to noisy problems, where they have turned out to be particularly robust. Theoretical results on the behavior of EAs for noisy functions are comparatively very rare, especially for di...

I report the status of the dynamical overlap fermion project by the JLQCD and TWQCD collaborations. So far, the simulations have been completed with two flavors of overlap sea quarks in a wide range of sea quark mass corresponding to the p-regime and the ε-regime on a 163 ×32 lattice at a =0.12 fm. More recently, runs with 2+1 flavors of sea quarks have also started. This talk mainly discusses ...
