Optimal Wiring on Rectangular Structure
نویسندگان
چکیده
In this paper we worked upon on optimal wiring on rectangular structure. Here we are given a rectangle partitioned into smaller rectangles by axis-parallel line segments. Find a subset of the segments such that the resulting structure from these segments is connected and it touches every smaller rectangle. Here we reduce the problem of exact cover by 3-sets (X3C), which is known to be NP-complete, into this problem and thus claim wiring problem to be NP-hard. This problem carries a special importance because very few problems in the domain of geometry are known to be NP-hard.

VLSI module placement based on rectangle-packing by the sequence-pair
The earliest and the most critical stage in VLSI layout design is the placement. The background of which is the rectangle packing problem: Given set of rectangular modules of arbitrary sizes, place them without overlap on a plane within a rectangle of minimum area. Since the variety of the packing is uncountably infinite, the key issue for successful optimization is the introduction of a finite...
متن کاملWiring optimization can relate neuronal structure and function.
We pursue the hypothesis that neuronal placement in animals minimizes wiring costs for given functional constraints, as specified by synaptic connectivity. Using a newly compiled version of the Caenorhabditis elegans wiring diagram, we solve for the optimal layout of 279 nonpharyngeal neurons. In the optimal layout, most neurons are located close to their actual positions, suggesting that wirin...
متن کاملWiring Economy of Pyramidal Cells in the Juvenile Rat Somatosensory Cortex
Ever since Cajal hypothesized that the structure of neurons is designed in such a way as to save space, time and matter, numerous researchers have analyzed wiring properties at different scales of brain organization. Here we test the hypothesis that individual pyramidal cells, the most abundant type of neuron in the cerebral cortex, optimize brain connectivity in terms of wiring length. In this...
متن کاملLarge amplitude vibration prediction of rectangular plates by an optimal artificial neural network (ANN)
In this paper, nonlinear equations of motion for laminated composite rectangular plates based on the first order shear deformation theory were derived. Using a perturbation method, the nonlinear equation of motion was solved and analytical relations were obtained for natural and nonlinear frequencies. After proving the validity of the obtained analytical relations, as an alternative and simple ...
متن کاملOptimization of shield structures in analog integrated circuits
The effect of shield structures for local wirings of analog integrated circuits on crosstalk is determined by electromagnetic simulation. The crosstalk of parallel wirings is reduced to -70 dB by the shield above and between the wirings. The optimal shield structure and terminal-impedance dependence are determined by numerical analysis taking terminal impedance as well as wiring length and widt...
