  • A Note on the Descent Property Theorem for the Hybrid Conjugate Gradient Algorithm CCOMB Proposed by Andrei 

    Nosratipour, Hadi؛ Sarani, Farhad (Damghan Universityدانشگاه دامغان, 2018-01-01)
    In [1] (Hybrid Conjugate Gradient Algorithm for Unconstrained Optimization J. Optimization. Theory Appl. 141 (2009) 249 - 264), an efficient hybrid conjugate gradient algorithm, the CCOMB algorithm is proposed for solving ...

  • A New Optimal Solution Concept for Fuzzy Optimal Control Problems 

    Soolaki, Javad؛ Soolaki, Mohammad (Damghan Universityدانشگاه دامغان, 2018-01-01)
    In this paper, we propose the new concept of optimal solution for fuzzy variational problems based on the possibility and necessity measures. Inspired by the well–known embedding theorem, we can transform the fuzzy variational ...

  • Some Results on Baer's Theorem 

    Faramarzi Salles, Asadollah (Damghan Universityدانشگاه دامغان, 2018-01-01)
    Baer has shown that, for a group G, finiteness of G=Zi(G) implies finiteness of ɣi+1(G). In this paper we will show that the converse is true provided that G=Zi(G) is finitely generated. In particular, when G is a finite ...

  • A Method for Solving Optimal Control Problems Using Genetic Programming 

    Bani, Ali Akbar؛ Darbani, Maliheh (Damghan Universityدانشگاه دامغان, 2018-01-01)
    This paper deals with a novel method for solving optimal control problems based on genetic programming. This approach produces some trial solutions and seeks the best of them. If the solution cannot be expressed in a closed ...

  • On Marginal Automorphisms of a Group Fixing the Certain Subgroup 

    nasrabadi, mahammad mehdi؛ hajizade, samane (Damghan Universityدانشگاه دامغان, 2018-01-01)
    Let W be a variety of groups defined by a set W of laws and G be a finite p-group in W. The automorphism α of a group G is said to bea marginal automorphism (with respect to W), if for all x ∈ G, x−1α(x) ∈ W∗(G), where ...
