Search results clustering problem is defined as an automatic, on-line grouping of similar documents in a search hits list, returned from a search engine. In this paper we present the results of an experimental evaluation of a new algorithm named Lingo. We use Open Directory Project as a source of high-quality narrowtopic document references and mix them into several multi-topic test sets for th...

Logic programming requires that the programmer convert a problem into a set of constraints based on predicates. Choosing the predicates and introducing appropriate constraints can be intricate and error-prone. If the problem domain is structured enough, we can let the programmer express the problem in terms of more abstract, higherlevel constraints. A compiler can then convert the higher-level ...

Myocilin is a secreted glycoprotein that belongs to a family of olfactomedin domain-containing proteins. Although myocilin is detected in several ocular and nonocular tissues, the only reported human pathology related to mutations in the MYOCILIN gene is primary open-angle glaucoma. Functions of myocilin are poorly understood. Here we demonstrate that myocilin is a mediator of oligodendrocyte d...

SMILES strings are the most compact text based molecular representations. Implicitly they contain the information needed to compute all kinds of molecular structures and, thus, molecular properties derived from these structures. We show that this implicit information can be accessed directly at SMILES string level without the need to apply explicit time-consuming conversion of the SMILES string...

This study presents a novel problem called green travelling salesman problem (GTSP), an extension of the classical travelling salesman problem (TSP). Proposed GTSP considers not just for the route distance, also accounts emitted CO2, consumed fuel, travelling times/speed and their costs with a more comprehensive objective function. The aim of this study is to shed light on the trade-offs betwee...
