Initialization of metaheuristics: comprehensive review, critical analysis, and research directions
International Transactions in Operational Research, Volume 30, Issue 6, Page 3361-3397, November 2023., 2023 Abstract Initialization of metaheuristics is a crucial topic that lacks a comprehensive and systematic review of the state of the art. Providing such a review requires in‐depth study and knowledge of the advances and challenges in the broader field of metaheuristics, especially with regard to diversification strategies, in order to assess the proposed ...

The 25th and 26th Mersenne Primes [PDF]
Mathematics of Computation, 1980 The 25th and 26th Mersenne primes are 2 21701 − 1 {2^{21701}} - 1 and 2 23209 − 1 {2^{23209}} - 1 , respectively.

Partitions of numbers and the algebraic principle of Mersenne, Fermat and even perfect numbers [PDF]
Notes on Number Theory and Discrete MathematicsLet ρ be an odd prime greater than or equal to 11. In a previous work, starting from an M-cycle in a finite field 𝔽_ρ, it has been established how the divisors of Mersenne, Fermat and Lehmer numbers arise.

Magnetic Resonance in Medicine, Volume 90, Issue 3, Page 1041-1052, September 2023., 2023 Purpose To develop and evaluate a 3D sector‐wise golden‐angle (3D‐SWIG) profile ordering scheme for cardiovascular MR cine imaging that maintains high k‐space uniformity after electrocardiogram (ECG) binning. Method Cardiovascular MR (CMR) was performed at 1.5 T. A balanced SSFP pulse sequence was implemented with a novel 3D‐SWIG radial ordering, where

A framework for cryptographic problems from linear algebra
Journal of Mathematical Cryptology, 2020 We introduce a general framework encompassing the main hard problems emerging in lattice-based cryptography, which naturally includes the recently proposed Mersenne prime cryptosystem, but also problems coming from code-based cryptography.

Autocorrelation and Lower Bound on the 2-Adic Complexity of LSB Sequence of
IEEE Access, 2020 LSB (Least Significant Bit) sequences are widely used as the initial inputs in some modern stream ciphers, such as the ZUC algorithm-the core of the 3GPP LTE International Encryption Standard. Therefore, analyzing the statistical properties (for example,

On recognition of simple group L2(r) by the number of Sylow subgroups
Acta Scientiarum: Technology, 2014 Let G be a finite group and n_{p}(G) be the number of Sylow p- subgroup of G. In this work it is proved if G is a centerless group and n_{p}(G)=n_{p}(L_{2}(r)), for every prime p in pi (G), where r is prime number, r^2 does not divide |G| and r is not ...

On Triangular Secure Domination Number
InPrime, 2020 Let T_m=(V(T_m), E(T_m)) be a triangular grid graph of m ϵ N level. The order of graph T_m is called a triangular number. A subset T of V(T_m) is a dominating set of T_m if for all u_V(T_m)\T, there exists vϵT such that uv ϵ E(T_m), that is, N[T]=V(T_m).
