    On the complexity of finding paths in a two‐dimensional domain I: Shortest paths.Arthur W. Chou & Ker-I. Ko - 2004 - Mathematical Logic Quarterly 50 (6):551-572.
    The computational complexity of finding a shortest path in a two-dimensional domain is studied in the Turing machine-based computational model and in the discrete complexity theory. This problem is studied with respect to two formulations of polynomial-time computable two-dimensional domains: domains with polynomialtime computable boundaries, and polynomial-time recognizable domains with polynomial-time computable distance functions. It is proved that the shortest path problem has the polynomial-space upper bound for domains of both type and type ; and it (...)

    Importance of Path Planning Variability: A Simulation Study.Jeffrey L. Krichmar & Chuanxiuyue He - 2023 - Topics in Cognitive Science 15 (1):139-162.
    Individuals vary in the way they navigate through space. Some take novel shortcuts, while others rely on known routes to find their way around. We wondered how and why there is so much variation in the population. To address this, we first compared the trajectories of 368 human subjects navigating a virtual maze with simulated trajectories. The simulated trajectories were generated by strategy-based path planning algorithms from robotics. Based on the similarities between human trajectories and different strategy-based simulated trajectories, (...)

    Smooth Path Planning for Robot Docking in Unknown Environment with Obstacles.Peng Cui, Weisheng Yan, Rongxin Cui & Jiahui Yu - 2018 - Complexity 2018:1-17.
    This paper presents an integrated approach to plan smooth path for robots docking in unknown environments with obstacles. To determine the smooth collision-free path in obstacle environment, a tree structure with heuristic expanding strategy is designed as the foundation of path planning in this approach. The tree employs 3D Dubins curves as its branches and foundation for path feasibility evaluation. For the efficiency of the tree expanding in obstacle environment, intermediate nodes and collision-free branches are determined (...)

    A novel method to find the best path in SDN using firefly algorithm.Hanan Abbas Salman & Tameem Hameed Obaida - 2022 - Journal of Intelligent Systems 31 (1):902-914.
    Over the previous three decades, the area of computer networks has progressed significantly, from traditional static networks to dynamically designed architecture. The primary purpose of software-defined networking is to create an open, programmable network. Conventional network devices, such as routers and switches, may make routing decisions and forward packets; however, SDN divides these components into the Data plane and the Control plane by splitting distinct features away. As a result, switches can only forward packets and cannot make routing decisions; the (...)

    Transformations in philosophy and legal practice.Suki Finn, Jill Marshall, Anna Pathe-Smith & Victoria Adkins - 2023 - In Suki Finn, Jill Marshall, Anna Pathe-Smith & Victoria Adkins (eds.), Transformations in philosophy and legal practice.
    This chapter provides a historical account of the transformation of pregnancy through philosophical theory and legal practice. What has remained seemingly consistent across history, though, is the lack of rights a pregnant woman can enjoy. Whilst it may manifest differently across time and place, unfortunately misogynistic attitudes persist, and this is reflected in the continual degrading of the gestator (and gestation), which is reinforced by certain philosophical theorising and technological advancement. We thus urge caution in making philosophical claims about the (...)

    A novel memetic algorithm for solving the generalized traveling salesman problem.Ovidiu Cosma, Petrică C. Pop & Laura Cosma - forthcoming - Logic Journal of the IGPL.
    This paper investigates the Generalized Traveling Salesman Problem (GTSP), which is an extension of the well-known Traveling Salesman Problem (TSP), and it searches for an optimal tour in a clustered graph, such that every cluster is visited exactly once. In this paper, we describe a novel Memetic Algorithm (MA) for solving efficiently the GTSP. Our proposed MA has at its core a genetic algorithm (GA), completed by a Chromosome Enhancement Procedure (CEP), which is based on a TSP solver and the (...)

  25. Vagueness has no function in law.Roy Sorensen - 2001 - Legal Thoery 7 (4):385--415.
    Islamic building codes require mosques to face Mecca. The further Islam spreads, the more apt are believers to fall into a quandary. X faces Y only when the front of X is closer to Y than any other side of X. So the front of the mosque should be oriented along a shortest path to Mecca. Which way is that? Does the path to Mecca tunnel through the earth? Or does the path follow the surface of (...)

    Dna computing, computation complexity and problem of biological evolution rate.Alexey V. Melkikh - 2008 - Acta Biotheoretica 56 (4):285-295.
    An analogy between the evolution of organisms and some complex computational problems (cryptosystem cracking, determination of the shortest path in a graph) is considered. It is shown that in the absence of a priori information about possible species of organisms such a problem is complex (is rated in the class NP) and cannot be solved in a polynomial number of steps. This conclusion suggests the need for re-examination of evolution mechanisms. Ideas of a deterministic approach to the evolution (...)

    The Teaching of Philosophy at Moscow University at the Beginning of the Twentieth Century.I. G. Novoselov - 2003 - Russian Studies in Philosophy 42 (2):89-99.
    For almost the whole of the first half of the nineteenth century, philosophy at Moscow University was subjected to fierce persecution at the hands of the authorities. Their aim was, evidently, to smother in the cradle any manifestation of freethinking among students, the thinking part of Russian society. It was no coincidence that philosophy was chosen as the target of persecution, because the study of this science could lead by the shortest path to reflections concerning man's place in (...)

    In praise of mathematics.Alain Badiou - 2016 - Malden, MA: Polity Press. Edited by Gilles Haéri & Susan Spitzer.
    Why bother to praise mathematics when you claim, as Alain Badiou does, that philosophy is first and foremost a metaphysics of happiness, or else it’s not worth an hour of trouble? What possible relationship can there be between mathematics and happiness? That is precisely the issue at stake in this dialogue, which serves as a very accessible introduction to what mathematics is and an exploration of the crucial influence it has always exerted on the greatest philosophers. Far from the thankless, (...)

    An elementary approach to design and analysis of algorithms.L. R. Vermani - 2019 - New Jersey: World Scientific. Edited by Shalini Vermani.
    In computer science, an algorithm is an unambiguous specification of how to solve a class of problems. Algorithms can perform calculation, data processing and automated reasoning tasks. As an effective method, an algorithm can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, (...)

    Understanding the Dynamics of Knowledge Building Process in Online Knowledge-Sharing Platform: A Structural Analysis of Zhihu Tag Network.Yongning Li, Lun Zhang & Ye Wu - 2022 - Complexity 2022:1-11.
    Through structural analysis of 8-year tag networks from online knowledge-sharing platforms, this study finds that, with the scale of tag networks growing quickly, the growth trend of number edges indicates that tag network follows densification law. The clustering coefficient and the average shortest path of the network show that the rapid growth of network size does not bring about the compartmentalization of the knowledge network, and the degree distribution of tag networks shows a truncated power-law distribution. According to (...)

    A measure of bizarreness.Christopher Chambers & Alan D. Miller - manuscript
    We introduce a path-based measure of convexity to be used in assessing the compactness of legislative districts. Our measure is the probability that a district will contain the shortest path between a randomly selected pair of its' points. The measure is defined relative to exogenous political boundaries and population distributions.

    This paper presents an axiomatization of a class of set-theoretic conditional operators using minimization of the geodesic distance defined as the shortest path generated by the accessibility relation on a frame. The objective of this modeling is to define conditioning based on a notion of similarity generated by degrees of indistinguishability.

    Heuristic evaluation functions in artificial intelligence search algorithms.Richard E. Korf - 1995 - Minds and Machines 5 (4):489-498.
    We consider a special case of heuristics, namely numeric heuristic evaluation functions, and their use in artificial intelligence search algorithms. The problems they are applied to fall into three general classes: single-agent path-finding problems, two-player games, and constraint-satisfaction problems. In a single-agent path-finding problem, such as the Fifteen Puzzle or the travelling salesman problem, a single agent searches for a shortest path from an initial state to a goal state. Two-player games, such as chess and checkers, (...)

    Geodesic merging.Konstantinos Georgatos - 2018 - Synthese 195 (10):4243-4264.
    We pursue an account of merging through the use of geodesic semantics, the semantics based on the length of the shortest path on a graph. This approach has been fruitful in other areas of belief change such as revision and update. To this end, we introduce three binary merging operators of propositions defined on the graph of their valuations and we characterize them with a finite set of postulates.

    A Novel Routing Control Technique for the Energy Hole in the Underwater Acoustic Distributed Network.Dong Xiao, Min Zhao, Ning Jia, Tong-Rui Peng, Yan Chen & Li Ma - 2021 - Complexity 2021:1-10.
    The energy hole is a severe problem for underwater acoustic distributed networks in that it affects the normal operations of the network and shortens the network’s life span. To deal with this problem, a loop-free routing control technique is proposed in this paper. The classical shortest-path routing control method is used to generate multiple disjointed routing tables. The residual energy of the nodes and the changing information of the uplink/downlink matrix are added to the data frames for distribution. (...)

In the field of our research here, emphasis was placed on extracting weights that would affect the speed of the network's response and finding the best path, such as the number of nodes in the path and the congestion on each path, in addition to the cache used for each node. Therefore, the use of these elements in (...)

    Disciplinary Networks and Bounding: Scientific Communication Between Science and Technology Studies and the History of Science. [REVIEW]Frédéric Vandermoere & Raf Vanderstraeten - 2012 - Minerva 50 (4):451-470.
    This article examines the communication networks within and between science and technology studies (STS) and the history of science. In particular, journal relatedness data are used to analyze some of the structural features of their disciplinary identities and relationships. The results first show that, although the history of science is more than half a century older than STS, the size of the STS network is more than twice that of the history of science network.

  44. Seeing and speaking: How verbal 'description length' encodes visual complexity.Zekun Sun & Chaz Firestone - 2021 - Journal of Experimental Psychology: General (1):82-96.
    What is the relationship between complexity in the world and complexity in the mind? Intuitively, increasingly complex objects and events should give rise to increasingly complex mental representations (or perhaps a plateau in complexity after a certain point). However, a counterintuitive possibility with roots in information theory is an inverted U-shaped relationship between the “objective” complexity of some stimulus and the complexity of its mental representation, because excessively complex patterns might be characterized by surprisingly short computational descriptions (e.g., if they (...)

    This study aimed to explore practices and strategies that have successfully reduced time-to-proficiency of the workforce in large multinational organisations and develop a model based on them. The central research question of this study was: How can organisations accelerate time-to-proficiency of employees in the workplace? The study addressed three aspects: the meaning of accelerated proficiency, as seen by business leaders; the business factors driving the need for shorter time-to-proficiency and benefits accrued from it; and practices and strategies to shorten time-to-proficiency (...)

    Probability of Disease Extinction or Outbreak in a Stochastic Epidemic Model for West Nile Virus Dynamics in Birds.Milliward Maliyoni - 2020 - Acta Biotheoretica 69 (2):91-116.
    Thresholds for disease extinction provide essential information for the prevention and control of diseases. In this paper, a stochastic epidemic model, a continuous-time Markov chain, for the transmission dynamics of West Nile virus in birds is developed based on the assumptions of its analogous deterministic model. The branching process is applied to derive the extinction threshold for the stochastic model and conditions for disease extinction or persistence. The probability of disease extinction computed from the branching process is shown to be (...)
