The Art Gallery Problem is one of the most well-known problems in Computational Geometry, with a rich history in the study of algorithms, complexity, and variants. Recently there has been a surge in experimental work on the problem. In this survey, we describe this work, show the chronology of developments, and compare current algorithms, including two unpublished versions, in an exhaustive exp...

We present first experiences from Local Area Artworks, a system enabling collaborative art interpretation on-site, deployed during an exhibition in a local art gallery. Through the system, we explore ways to re-connect people to local places by making use of their personal mobile devices as interfaces to the shared physical space. With a collocated collaborative writing system in the semi-publi...

This study aims to analyze knowledge, risk and motivation influence interest in investing the UHAMKA Investment Gallery with subject of management program FEB UHAMKA. Hypothesis testing using multiple linear regression analysis classical assumption testing. The sampling technique used is simple random data collection techniques carried out by giving a questionnaire an online google application ...

We prove two art gallery theorems in which the guards must guard one another in addition to the gallery. A set G of points (the guards) in a simple closed polygon (the art gallery) is a guarded guard set provided (i) every point in the polygon is visible to some point in G; and (ii) every point in G is visible to some other point in G. We prove that a polygon with n sides always has a guarded g...

Let bd(P ) denote the boundary of a simple polygon P . Points p and q of P are mutually visible if segment pq lies entirely inside P . This notion of visibility gave birth to an extensive literature on art-gallery problems [3], concerned with guarding the floor of a polygonal art-gallery. Chvatal [2] showed that bn/3c point guards are always sufficient and sometimes necessary. Allowing guards t...

Grotta dei Cervi is a cave which opens into the Oligocenic Calcarenites at 26 m above sea level on the channel of Otranto, 370 m NE of Porto Badisco, Lecce, southeastern Italy. It was discovered on February 1, 1970. From the geomorphological point of view, the cave is the site of an ancient underground water table. The innumerable concavities which are visible on the roof of the gallery have fo...

Parametric computer-aided design (CAD) is a standard paradigm used to manufactured objects, where 3D shape represented as program supported by the CAD software. Despite pervasiveness of parametric and growing interest from research community, currently there does not exist dataset realistic models in concise programmatic form. In this paper we present Fusion 360 Gallery , consisting simple lang...
