A multiagent application consists of an environment and a number of agents. The environment contains information that the agents use and manipulate to do their work. When a multiagent system is decentralized over a number of different hosts (i.e. more than one execution platform is used), the environment has to be decentralized as well. The distributed layout of the environment can influence th...

Constraints have played an important role in the construction of GUIs, where they are mainly used to define the layout of the widgets. Resizing behavior is very important in GUIs because areas have domain specific parameters such as form the resizing of windows. If linear objective function is used and window is resized then error is not distributed equally. To distribute the error equally, a q...

The paper describes the application of a genetic engineering based extension to genetic algorithms to the layout planning problem. We study the gene evolution which takes place when an algorithm of this type is running and demonstrate that in many cases it e ectively leads to the partial decomposition of the layout problem by grouping some activities together and optimally placing these groups ...

Procedural content generation is becoming more and more relevant to solve the problem of content creation for the ever growing virtual worlds of games, simulations and other applications. However, these procedures are often unintuitive or use vague parameters, making it somewhat difficult for a designer to express his or her creative intent. Even worse, most of these techniques lack an accessib...

In this paper, a number of symmetry-breaking (SB) constraints are considered to improve the performance and decrease computational effort needed in the solution of Process Plant Layout (PPL) Problems. The PPL problems are formulated as mixed-integer linear (MILP) models. In order to determine the efficiency of the symmetry-breaking formulations, test runs are carried out on three different prob...

A bay configuration arranged along a central spine and served by an automated monorail material handling system are common designs for the layout and material handling system in new semiconductor wafer fabrication facilities. This paper investigates the facility design problem in semiconductor fabrication facilities and proposes a procedure to determine the optimal spine layout design given a d...

Cellular manufacturing system design has received much attention for the past three decades. The design process involves decisions on (i) cell formation, (ii) cell layout, and (iii) layout of cells on the shop floor. These decisions should be addressed jointly, if full benefits of cellular manufacturing are to be realised. However, due to the complexity of the problem, most researchers addresse...

Development of application front-ends that are designed for deployment on multiple devices requires facilities for specifying deviceindependent semantics. This paper focuses on the user-interface requirements for specifying device-independent layout constraints. We describe a device independent application model, and detail a set of high-level constraints that support automated layout on a wide...

We are interested in the problem of text layout as it relates to our work on the intelligent generation of integrated text and information graphics (e.g., tables, bar charts, plots, maps) the AutoBrief system (Kerpedjiev et al. 1997; Green, Carenini, & Moore 1998; Green et al. 1998). Intelligent layout generation is related to the problems of media allocation and cross-media cue generation. We ...

The definition of presentation layout, based on device and user features, can be useful to provide multidevices content adaptation capabilities for hypervideos presentations. We provide a possible approach of content adaptation through different devices using MPEG-4 as presentation framework. In particular, we focus on the use of adaptable interfaces in hypervideos presentations, separating lay...
