CentralNotice Logistics From Wikipedia, the free encyclopedia Jump to: navigation , search Logistics is the management of the flow of goods between the point of origin and the point of consumption in order to meet some requirements, of customers or corporations. The resources managed in logistics can include physical items, such as food, materials, animals, equipment and liquids, as well as abstract items, such as time, information, particles, and energy. The logistics of physical items usually involves the integration of information flow, material handling , production , packaging , inventory , transportation , warehousing , and often security . The complexity of logistics can be modeled, analyzed, visualized, and optimized by dedicated simulation software . The minimization of the use of resources is a common motivation in logistics for import and export. Configuri...

CentralNotice Eulerian path From Wikipedia, the free encyclopedia Jump to: navigation , search The Königsberg Bridges graph. This graph is not Eulerian, therefore, a solution does not exist. Every vertex of this graph has an even degree , therefore this is an Eulerian graph. Following the edges in alphabetical order gives an Eulerian circuit/cycle. In graph theory , a Eulerian trail (or Eulerian path ) is a trail in a graph which visits every edge exactly once. Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail which starts and ends on the same vertex . They were first discussed by Leonhard Euler while solving the famous Seven Bridges of Königsberg problem in 1736. Mathematically the problem can be stated like this: Given the graph in the image, is it possible to construct a path (or a cycle , i.e. a path starting and ending on the same v...

CentralNotice Hamiltonian path From Wikipedia, the free encyclopedia Jump to: navigation , search This article is about the overall graph theory concept of a Hamiltonian path. For the specific problem of determining whether a Hamiltonian path or cycle exists in a given graph, see Hamiltonian path problem . A Hamiltonian cycle in a dodecahedron . Like all platonic solids , the dodecahedron is Hamiltonian. The Herschel graph is the smallest possible polyhedral graph that does not have a Hamiltonian cycle. In the mathematical field of graph theory , a Hamiltonian path (or traceable path ) is a path in an undirected or directed graph that visits each vertex exactly once. A Hamiltonian cycle (or Hamiltonian circuit ) is a Hamiltonian path that is a cycle . Determining whether such paths and cycles exist in graphs is the Hamiltonian path problem , which is NP-com...

CentralNotice Curse of dimensionality From Wikipedia, the free encyclopedia Jump to: navigation , search The curse of dimensionality refers to various phenomena that arise when analyzing and organizing data in high-dimensional spaces (often with hundreds or thousands of dimensions) that do not occur in low-dimensional settings such as the three-dimensional physical space of everyday experience. There are multiple phenomena referred to by this name in domains such as numerical analysis , sampling , combinatorics , machine learning , data mining and databases . The common theme of these problems is that when the dimensionality increases, the volume of the space increases so fast that the available data become sparse. This sparsity is problematic for any method that requires statistical significance. In order to obtain a statistically sound and reliable result, the amount...

CentralNotice NP-hard From Wikipedia, the free encyclopedia Jump to: navigation , search For a gentler introduction, see P versus NP problem . Euler diagram for P , NP , NP-complete , and NP-hard set of problems NP-hard ( N on-deterministic P olynomial-time hard), in computational complexity theory , is a class of problems that are, informally, "at least as hard as the hardest problems in NP". More precisely, a problem H is NP-hard when every problem L in NP can be reduced in polynomial time to H . [ 1 ] :80 As a consequence, finding a polynomial algorithm to solve any NP-hard problem would give polynomial algorithms for all the problems in NP, which is unlikely as many of them are considered as hard. [ 2 ] A common mistake is to think that the NP in NP-hard stands for non-polynomial . Although it is widely suspected that there are no polynomial-time algorithms ...
