Understanding the "Chain Rule" by Deriving Your Own Version

Authors: James A. Smith
Comments: 12 Pages.

Because the Chain Rule can confuse students as much as it helps them solve real problems, we put ourselves in the shoes of the mathematicians who derived it, so that students may understand the motivation for the rule; its limitations; and why textbooks present it in its customary form. We begin by finding the derivative of sin2x without using the Chain Rule. That exercise, having shown that even a comparatively simple compound function can be bothersome to differentiate using the definition of the derivative as a limit, provides the motivation for developing our own formula for the derivative of the general compound function g[f(x)]. In the course of that development, we see why the function f must be continuous at any value of x to which the formula is applied. We finish by comparing our formula to that which is commonly given.

Significant Generalization of the Convergence Proof for the Direct Transcription Method for Constrained Optimal Control Problems

Authors: Martin Peter Neuenhofen
Comments: 13 Pages. Proof of convergence for a direct transcription method for OCP

In the arXiv paper [arXiv:1712.07761] from December 2017 we presented a convergent direct transcription method for optimal control problems. In the present paper we present a significantly generalized convergence theory in succinct form. Therein, we replace strong assumptions that we had formerly made on local uniqueness of the solution, and on differentiability of a particular functional. These assumptions are removed now.

Shellability is NP-complete

Authors: Thinh Nguyen
Comments: 19 Pages.

We prove that for every d≥2, deciding if a pure, d-dimensional, simplicial complex is shellable is NP-hard, hence NP-complete. This resolves a question raised, e.g., by Danaraj and Klee in 1978. Our reduction also yields that for every d≥2 and k≥0, deciding if a pure, d-dimensional, simplicial complex is k-decomposable is NP-hard. For d≥ 3, both problems remain NP-hard when restricted to contractible pure d-dimensional complexes. Another simple corollary of our result is that it is NP-hard to decide whether a given poset is CL- shellable.

Erd ̋os-Szekeres is NP-Hard in 3 Dimensions and What Now?

Authors: Thinh Nguyen
Comments: 4 Pages.

The Erd ̋os-Szekeres theorem states that, for every $k$, there is a number $n_k$ such that every set of $n_k$ points in general position in the plane contains a subset of $k$ points in convex position. If we ask the same question for subsets whose convex hull does not contain any other point from the set, this is not true: as shown by Horton, there are sets of arbitrary size that do not contain an empty 7-gon. These questions have also been studied extensively from a computational point of view, and polynomial time algorithms for finding the largest (empty) convex set have been given for the planar case. In higher dimension, it is not known how to compute such a set efficiently. In this paper, we show that already in 3 dimensions no polynomial time algorithm exists for determining the largest (empty) convex set (unless $P$=$NP$), by proving that the corresponding decision problem is $NP$-hard. This answers a question by Dobkin, Edelsbrunner and Overmars from 1990. As a corollary, we derive a similar result for the closely related problem of testing weak $ε$-nets in $R^3$ . Answering a question by Chazelle et al. from 1995, our reduction shows that the problem is $co-NP$-hard. Finally, we make several suggestions for further research on the subject.

The Unreasonable Expectation of Mathematics

Authors: A. Lau
Comments: 6 Pages.

Abstract. Mathematics has been highly effective in its application of formalism to the real world. It spans from physical science to data science. Mathematical algorithm affects our everyday life. Mathematization (converting data to equations or mathematical forms) has been very successful. It has led to comments like “the unreasonable effectiveness of mathematics,” but we might have “unreasonable expectation of mathematics.”

The Majority Rule and Combinatorial Geometry (Via the Symmetric Group)

Authors: Thinh Nguyen
Comments: 0 Pages.

The Marquis du Condorcet recognized 200 years ago that majority rule can produce intransitive group preferences if the domain of possible (transitive) individual preference orders is unrestricted. We present results on the cardinality and structure of those maximal sets of permutations for which majority rule produces transitive results (consistent sets). Consistent sets that contain a maximal chain in the Weak Bruhat Order inherit from it an upper semimodular sublattice structure. They are intrinsically related to a special class of hamiltonian graphs called persistent graphs. These graphs in turn have a clean geometric interpretation: they are precisely visibility graphs of staircase polygons. We highlight the main tools used to prove these connections and indicate possible social choice and computational research directions.

Derivation of the Limits of Sine and Cosine at Infinity

Authors: Jonathan W. Tooker
Comments: 4 Pages. two figures

This paper examines some familiar results from complex analysis in the framework of hypercomplex analysis. It is usually taught that the oscillatory behavior of sine waves means that they have no limit at infinity but here we derive definite limits. Where a central element in the foundations of complex analysis is that the complex conjugate of a $^\star\mathbb{C}$-number is not analytic at the origin, we introduce the tools of hypercomplex analysis to show that the complex conjugate of a $^\star\mathbb{C}$-number is analytic at the origin.

Fundamentals of Neutrosophic Logic and Sets and Their Role in Artificial Intelligence

Authors: Florentin Smarandache, Maikel Leyva-Vázquez
Comments: 6 Pages.

Neutrosophy is a new branch of philosophy which studies the origin, nature and scope of neutralities. This has formed the basis for a series of mathematical theories that generalize the classical and fuzzy theories such as the neutrosophic sets and the neutrosophic logic. In the paper, the fundamental concepts related to neutrosophy and its antecedents are presented. Additionally, fundamental concepts of artificial intelligence will be defined and how neutrosophy has come to strengthen this discipline.

In this work, elements related to mental models elicitation and analysis are addressed through causal models. Issues related to the need to include indeterminacy in causal relationships through neutrophic cognitive maps are discussed. A proposal for static analysis in neutrosophic cognitive maps is presented. The following activities are included in the proposal: Calculate, measures of centrality, Classify nodes, De-neutrosification, and Ranking nodes. As future works, the incorporation of new metrics of centrality in neutrosophic cognitive maps is proposed. The inclusion of scenario analysis to the proposal is another area of future work.

Polynomial Encryption

Authors: Yeray Cachón Santana
Comments: 12 Pages. Feel free to send any comment to ycachon@gmail.com

This paper proposes a new method to encrypt and decrypt a message by special functions formed by Hermite, Laguerre, Tchebychev and Bessel The idea to encrypt a message will be by using base changes from the Taylor base to the bases of those special functions. The Hermite, Lagurrre, Tchebychev and Bessel polynomials are orthogonal, so they form a base set on a Hilbert space. The encryption will be using several sequences of those base changes according to a number sequence. According to Hilbert space, as those are orthogonal polynomials, those functions form a orthogonal base. So, a change base can be done between a Taylor base and those bases - this is the method that will be used in order to encrypt a message.

Refutation of Neutrosophy as Generalized from Hegel's Dialectic © Copyright 2018 by Colin James III All Rights Reserved.

Authors: Colin James III
Comments: 2 Pages. © Copyright 2018 by Colin James III All rights reserved. info@cec-services dot com

The argument as rendered is not tautologous and a contradiction. This refutes the definition of neutrosophy and consequently invalidates it as a generalization of Hegel's dialectic. Remark: Hegel's dialectical philosophy lacks a quantified and modalized symbolic logic; to map it into a modal logic model checker is hence potentially problematic.

Refutation of Quinary Logic in Neutrosophy © Copyright 2018 by Colin James III All Rights Reserved.

Authors: Colin James III
Comments: 1 Page. © Copyright 2018 by Colin James III All rights reserved. info@cec-services dot com

From the equations as rendered, the notion of ambiguity A (0.5,0.5) is not tautologous but rather truthity. Remark: The abstract of the captioned paper introduces the modal words of possibility and necessity which unfortunately are not mentioned in the text. We conclude that there is no provision in the neutrosophic cube to introduce modal operators. Because neutrosophy has no bivalent square of opposition, but rather a non-bivalent lozenge with a multiple-defined midpoint, the quantified operators are prohibited from definition and hence are disparate from neutrosophy. This means neutrosophic logic is unable to map and support modal or alethic logic.

Multi-criteria Group Decision Making based on Linguistic Refined Neutrosophic Strategy

Authors: Kalyan Mondal, Surapati Pramanik, Bibhas C. Giri
Comments: 15 Pages.

Multi-criteria group decision making (MCGDM) strategy, which consists of a group of experts acting collectively for best selection among all possible alternatives with respect to some criteria, is focused on in this study. To develop the paper, we define linguistic neutrosophic refine set. We also define entropy to calculate unknown weights of the criteria and establish basic properties of entropy in linguistic neutrosophy refine set environment. In the developed strategy, the rating of all alternatives is expressed with linguistic variables.

The Unreasonable Expectation of Mathematics

Authors: August Lau
Comments: 6 Pages.

Mathematics has been highly effective in its application of formalism to the real world. It spans from physical science to data science. Mathematical algorithm affects our everyday life. Mathematization (converting data to equations or mathematical forms) has been very successful. It has led to comments like “the unreasonable effectiveness of mathematics,” but we might have “unreasonable expectation of mathematics.”

Transformation of the Pixels in Tupper's Self-Referential Formula

Authors: Prathamesh Deshmukh
Comments: 33 Pages. This is my first research paper and I would like to have any suggestion or improvement for the paper

My research paper is "Transformation of the pixels in Tupper's self-referential formula " is Based on Tupper's self-referential formula, you might know this formula As it is popular due to its property of plotting itself. But that is not the only amazing thing about this formula, it doesn't only plot itself but it plots every possible combination of the pixels between k and k+17 on the y-axis and 0 to 106 on the x-axis I.e. it plots all possible combination of these 1802 pixels and the value of k is used for sliding over the y-axis My research idea start with a question that if there is some graphical formation at a particular value of k then what can do to change the graphical formation or to change its position, this question leads to my research which has two main ideas 1> How to change any graphical formation into other graphical formation by applying some kind of operation to the value of the k 2>How can this different graphical formation be used as a frame to create a film / motion picture So what can my research do 1> My research represent all the possible graphical (in 1802 pixels ) and all its possible variation I.e. it have every possible graphical formation which is converting into other possible graphical structure 2> You can create a formula for any film / motion picture 3> In short formulas in my research is like library of babel of film / motion picture
