Fabrication and programming of large physically evolving networks

چکیده
Physically Evolving Networks (PENs) were first proposed by Alan Turing in his 1948 paper “Intelligent Machines” [1]. PENs capture some important features of the information processing of biological neural systems, such as mimicking animal and human error patterns, and implement massively parallel, non-algorithmic processes, where the sequence and concurrency of operations is determined at run time. PENs simulations on conventional digital computers have been successfully used for speech recognition, image analysis, and adaptive control. But PEN implementations on computers with von Neumann architecture are slow compared to other algorithms which are optimized for the sequential processing of explicit instructions. In the following we discuss hardware implementations of PENs. Would it be possible to fabricate a PEN of the size of a human brain with a billion times more neurons? And if so, how could such a PEN be programmed or trained?

Optimal Design of the Cross-docking in Distribution Networks: Heuristic Solution Approach
A design problem of cross-docking distribution networks is addressed as a new research area in logistics management. This paper presents a new mathematical model for the location of cross-docking facilities and vehicle routing scheduling problems in distribution networks. For this purpose, a two-phase mixed-integer programming (MIP) is formulated. Then, a new heuristic-based simulated annealing...
متن کاملA DSS-Based Dynamic Programming for Finding Optimal Markets Using Neural Networks and Pricing
One of the substantial challenges in marketing efforts is determining optimal markets, specifically in market segmentation. The problem is more controversial in electronic commerce and electronic marketing. Consumer behaviour is influenced by different factors and thus varies in different time periods. These dynamic impacts lead to the uncertain behaviour of consumers and therefore harden the t...
