Social bots are defined as computer algorithms that generate massive amounts of obnoxious or meaningful information. Most bot detection methods leverage multitudinous characteristics, from network features, temporal dynamics activities and sentiment features. However, there has been fairly lower work exploring lexicon measurement linguistic indicators to detect bots. The main purpose this resea...

The obnoxious p-median problem is a facility location where we maximise the sum of distances between each client point and its nearest facility. Since it nondeterministic polynomial-time (NP)-hard, most algorithms designed for follow metaheuristic strategies to find high-quality solutions in affordable time but with no optimality guarantee. In this paper, variant iterated greedy algorithm devel...

The genus of Striga spp., particularly hermonthica, is an obligate root-hemiparasitic weed. affects 25 African countries annually and considered a major biotic threat to food security. This obnoxious weed species has been managed using various control strategies. However, the strategies have not highly effective due complexity life cycle special interactions with its host. Biological control, s...

My research field is Computational Geometry, and I am interested both in theoretical problems and in ‘real life’ applications. This statement includes a summary of my research work to date. The first part covers work involving L1 shortest paths, center point and obnoxious facility location (see [5], [6], [8]) most of this work was done during my Master studies [1999-2001], and is motivated by p...

The brain senses the world indirectly because the sense organs convert stimulation into the language of the nervous system: neural messages. We get used to all but the most extreme or obnoxious stimuli because our senses are built to tell us about change. The senses all operate in much the same way, but each extracts different information and sends it to its own specialized processing region in...

Forgotten attachments of e-mail message are a common and obnoxious problem. Several E-mail readers provide plugins that attempt to tackle this problem by trying to guess whether a message needs an attachment and warn the user in case s/he does not attach a file to such a message. However, these approaches essentially only work with a fixed list of keywords, which trigger such a warning whenever...

We use the ellipsoidal lp norm to measure the distance for both the desirable and the obnoxious facility location problems with constraints. The optimality conditions for both location models are derived. We give Newton’s method for the models. Finally, numerical examples are presented. ∗Center of Operations Research and Econometrics (CORE), Université catholique de Louvain [email protected]. 34 ...
