One of the well-known evolutionary algorithms inspired by biological evolution is genetic algorithm (GA) that is employed as a robust and global optimization tool to search for the best or near-optimal solution with the search space. In this paper, this algorithm is used to solve unequalsized machines (or intra-cell) layout problems considering pick-up and drop-off (input/output) points. Such p...

We present a new network diagram authoring tool, Dunnart, that provides continuous network layout. It continuously adjusts the layout in response to user interaction, while still maintaining the layout style and, where reasonable, the current layout topology. The diagram author uses placement constraints, such as alignment and distribution, to tailor the layout style and can guide the layout by...

The efficiency of desktop publishing is severely limited by the lack of sophisticated automatic document layout systems. State-of-the-art algorithms either require the input to be written in a description language such as HTML and LATEX, or to be a manually designed layout template. However, description languages are ill-suited to express layout problems with weak semantics and layout templates...

The large amount of secondary effects in complementary metal–oxide–semiconductor technology limits its application the ultra-nanoscale region. Circuit designers explore a new for region, which is quantum-dot cellular automata (QCA). Low-energy dissipation, high speed, and area efficiency are key features QCA technology. This research proposes novel, low-complexity, QCA-based one-bit digital com...

The objective of this research is to study plant layout of iron manufacturing based on the systematic layout planning pattern theory (SLP) for increased productivity. In this case study, amount of equipments and tools in iron production are studied. The detailed study of the plant layout such as operation process chart, flow of material and activity relationship chart has been investigated. The...

The common Arabic keyboard layout is derived from the Arabic typewriter keyboard’s layout. This layout is not optimized for typing speed and has several problems. We use a genetic algorithm to optimize the design of the Arabic keyboard layout for typing speed. In the genetic algorithm, we use a fitness function that includes into consideration key distance, finger used, and hand alternation. We...

Constrained graph layout is a recent generalisation of forcedirected graph layout which allows constraints on node placement. We give a constrained graph layout algorithm that takes an initial feasible layout and improves it while preserving the topology of the initial layout. The algorithm supports poly-line connectors and clusters. During layout the connectors and cluster boundaries act like ...

As technology continues to leap forward and innovations advance, the systems of civil aircraft are becoming increasingly sophisticated complex. Accordingly, there is a rising amount information be processed by pilots in cockpit, increasing their cognitive burden, which significantly threatens safety flight. Thus, designers have formulated cockpit layout principles relating importance, frequency...
