The layout of information is a complex task, and is usual-ly entrusted to a professional graphic designer. Research into automatic layout attempts to develop computational models of problem solving techniques used by graphic designers to solve layout problems. Graphic designers develop their problem solving skills through years of learning by following three approaches: i) learning by being tol...

Fig. 1. A scatterplot with extreme overplotting (left), with random jitter (middle) and the result from our constraint-based layout framework (right). Abstract—This work explores the connection between statistical data visualization problems and simulated physical systems. Applying techniques for constraint-based layout, data points are treated as physical objects under the influence of forces ...

Recently, an integral geometric method called the tube method has been actively developed. The tube method gives us a powerful tool to tackle problems where conventional matrix theory such as the singular value decomposition cannot be applied. The aim of this paper is to survey several recent applications of the tube method to distributional problems in multiway layouts mainly by the authors. N...

Multi-layer channel routing is one of cumbersome jobs in automatic layout design of VLSI chips and PCBs. As VLSI chips have been used in every field of electrical engineering, it becomes more important to reduce the layout design time. With the advancement of the VLSI technology, four-layer problems can be treated and the algorithms for more than four-layer problems will be demanded in the near...

Packing and layout problems have wide applications in engineering practice. However, they belong to NP (non-deterministic polynomial)-Complete problems. In this paper, we introduce human intelligence into the computational intelligent algorithms, namely particle swarm optimisation (PSO) and immune algorithms (IA). A novel human-computer cooperative PSO-based immune algorithm (HCPSO-IA) is propo...

One of the strategies used to optimize production processes is define best layout. For this, relative positioning various equipment, areas, or functional activities inside company studied. Proper arrangement facilities will result in shorter process times and higher productivity. In general, objective function facility layout problem (FLP) reduce total material handling cost. Although over six ...

s of the Presentations Solving inconsistencys preserving the zero-structure Paula Amaral, Joaquim Júdice and Hanif Sherali, University of Coimbra In this talk we describe an nonlinear optimization model for correcting an inconsistent linear system. By correction we mean a perturbation of both the matrix of coefficients and right-hand-side of the linear system of inequalities. Inconsistency of a...

The facility layout problem is a well researched one. However few effective and user friendly approaches have been proposed. Since it is an NP hard problem, various optimization approaches for small problems and heuristic approaches for the larger problems have been proposed. For the most part the more effective algorithms are not user friendly. On the other hand user friendly methods have not ...

Plant layout design is related to the location of facilities (e.g. machines, departments) in a plant. They are known to greatly impact the system performance. Numerous research works related to facility layout have been published. A few literature reviews exist, but they are not recent or are restricted to certain specific aspects of these layout design. The literature analysis given here is re...
