Metric indexes aim at reducing the amount of distance evaluations carried out when searching a metric space. Spatial approximation trees (sa-trees for short), in particular, are efficient data structures, which have shown to be competitive in metric spaces of medium to high difficulty, or queries with low selectivity. Sa-trees can be also made dynamic, and can use the available space to improve...

This paper presents a new stochastic approach for solving combinatorial optimization problems by using a new selection method, i.e. SA-selection, in genetic algorithm (GA). This approach combines GA with simulated annealing (SA) to improve the performance of GA. GA and SA have complementary strengths and weaknesses. While GA explores the search space by means of population of search points, it ...

The issue of stochastic reconstruction of chalk samples containing appreciable amount of vuggy porosity in the form of foraminifer shells using a conditional simulated annealing (SA) technique is addressed. A new indicator function suitable for the algorithm is defined to represent chalk microstructures. Most of the chalk samples consist of vuggy porosity associated with large cavities found in...

Automatic text summarization is a process to reduce the volume of text documents using computer programs to create a text summary with keeping the key terms of the documents. Due to cumulative growth of information and data, automatic text summarization technique needs to be applied in various domains. The approach helps in decreasing the quantity of the document without changing the context of...

H nuclear magnetic resonance (NMR) spectroscopy was utilized to distinguish the brands of rapeseed oils. As there are more than four hundreds of NMR variables which can cause the discrimination model redundancy, it is necessary to do effective variable selection. Successive projections algorithm (SPA) executed on the full spectrum only improved a few correct answer rate (CAR) and Cohen’s kappa ...

The term software architecture (SA) intuitively denotes the high level structures of a software system. It can be defined as the set of structures needed to reason about the software system, which comprise the software components and connectors, their relations and properties. Nowadays SA has become an important factor in the process of software development and the researches mainly focus on th...

Parcel delivery service by collect-on-delivery (COD, a.k.a. cash-on-delivery) companies is a new distribution mode in China. The design of the distribution network of a COD company in urban areas is of great importance and a relatively new research direction. In this paper, we aim to model this distribution network as a two-echelon location routing problem (2E-LRP) and propose a novel efficient...
