Let A be a finite alphabet, and H be a finite dictionary of words formed from the letters of this alphabet. In a conventional keyboard typically each key of the keyboard is assigned a unique symbol chosen from the alphabet. We consider the problem of assigning more than one symbol of the alphabet A to the same key on the keyboard. Let Ci be a subset of A. Every time a character in Ci is to be represented, the keyboard represents it using the digit (i.e. the index) 'i'. In a keyboard of this form, since multiple symbols of the alphabet A have the same representation, the representations of all the (distinct) words in the dictionary H need not be unique. A useful measure of the effectiveness of a particular keyboard is the number of words of H which are mapped to the same encoded form (i.e. they collide). This metric will be termed the ambiguity associated with the keyboard. The problem we study is one of optimally assigning the symbols of the alphabet to the keys of a given keyboard with a view to minimize the resulting ambiguity. The problem as stated above is proven to be NP-hard. This naturally leads us to seek fast and approximate solutions to the optimization problem on hand. After presenting the only reported solution to the problem, we report a fast learning automaton-based solution to this problem. Experimental results demonstrating the power of this solution have also been presented.

Effective economic dispatch for the integrated energy system (IES) can improve energy efficiency and promote renewable energy accommodation. Tradition IES economic dispatch are based on model-based methods that rely on accurate system parameters and uncertainty prediction. This paper proposes a data-driven fast economic dispatch method based on deep reinforcement learning (DRL) in an integrated electricity and natural gas system (IEGS). Unlike other DRL-based studies that spend a lot of computation time to calculate power flow, we employ DNNs to learn the complex nonlinear relationship existing in the IEGS, namely IEGSNet. Then, the economic dispatch problem is formulated as a Markov decision process, and solved by the soft actor-critic (SAC) algorithm. Simulation results illustrate that the proposed method achieves the similar operation cost to the tradition DRL-based dispatch method, but takes almost one tenth of the training time. Additionally, the computation time of the proposed method for 10-day dataset is at least two orders of magnitudes shorter that the model-based optimization algorithm.

Understanding the exceptional role of intelligent technologies and systems in the new digital economy has given rise to a new technological race - artificial intelligence. In emerging markets, artificial intelligence and intelligent technologies are, in fact, an integral part of cutting-edge management systems. They add to the globalization of business by providing quick access to employees, customers, and partners worldwide, as well as coordinating global interaction between companies at different stages of the value chain. It does not mean that intelligent technologies and systems simply increase the efficiency of a company's operations;they can be considered as a key intangible asset. The AI strategy is defined as a set of coordinated policies that have a clear objective of maximizing the potential benefits and minimizing the potential costs of AI for the economy and society. In the past few years, two dozen countries have launched their national strategies in the field of artificial intelligence. Many countries have already developed their AI strategy at the official level during the last 3 years. The main goal of this paper is the analysis of the emerging market multinational enterprises (EMNEs) AI strategies to support the emergent economy and identify key AI strategies development directions. The research is based on the analysis of large volumes of information, the author's own experience, and literature review that includes the latest findings in this field. Research Methodology includes a systematic approach, comparative analysis, case-study, and modeling. The problem the author considers here is: How can we reduce the impact of risks and uncertainty on the economic stability with the help of AI and how the emerging market multinational enterprises (EMNEs)' AI Strategies have already been successfully using the AI Strategies in the past fifteen years? The findings of the research are based on providing a framework for assessing the role of EMNEs' AI strate
