Designing Memristive Materials for Artificial Dynamic Intelligence
Key characteristics required of memristors for realizing next‐generation computing, along with modeling approaches employed to analyze their underlying mechanisms. These modeling techniques span from the atomic scale to the array scale and cover temporal scales ranging from picoseconds to microseconds. Hardware architectures inspired by neural networks

Study of TSP based on self-organizing map
Self-organizing map(SOM) proposed by Kohonen has obtained certain achievements in solving the traveling salesman problem(TSP).To improve Kohonen SOM,an effective initialization and parameter modification method is discussed to obtain a faster convergence

Quantum computing techniques such as Quantum Annealing and Quadratic Unconstrained Binary Optimization are effectively solving NP‐hard problems in operations management and research, particularly in logistics, manufacturing, and finance. This study maps these applications to present a framework for future adoption across industries. ABSTRACT This study

Approximating 1-dimensional TSP Requires Omega(n log n) Comparisons
We give a short proof that any comparison-based n^(1-epsilon)-approximation algorithm for the 1-dimensional Traveling Salesman Problem (TSP) requires Omega(n log n) comparisons.Comment: Superseded by "On the complexity of approximating Euclidean ...

In this paper, we have reviewed six distinct metaheuristic optimisation algorithms applicable to challenging problems in electromagnetics and optics. Specifically, we applied each method to the synthesis of GMR narrowband reflection filters and performed a systematic comparative evaluation. ABSTRACT The design of optical elements often requires precise

New Heuristic Approaches for the Min–Max Regret Traveling Salesman Problem
The traveling salesman problem (TSP) is widely known as one of the most important NP-hard combinatorial optimization problems. In this paper, we consider the min-max regret traveling salesman problem (MMR-TSP) with interval travel costs. The MMR-TSP aims

Combinatorial relaxation of the k-traveling salesman problem
The k-traveling salesman problem, or k-TSP is: given a graph with edge weights and an integer k, find a simple cycle of minimum weight visiting exactly k nodes. To obtain lower bounds for the traveling salesman problem the 2-matching relaxation and the 1-

Improving the Asymmetric TSP by Considering Graph Structure [PDF]
Recent works on cost based relaxations have improved Constraint Programming (CP) models for the Traveling Salesman Problem (TSP). We provide a short survey over solving asymmetric TSP with CP.

A New Cooperative Framework for Parallel Trajectory-Based Metaheuristics
In this paper, we propose the Parallel Elite Biased framework (PEB framework) for parallel trajectory-based metaheuristics. In the PEB framework, multiple search processes are executed concurrently.
