Special Issue Information

Dear Colleagues,

Smart cities and societies are underpinned by our ability to engage with our environments and analyse and make efficient, sustainable, and equitable decisions [1], [2]. The fundamental fabric of these smart cities and societies is built on smart devices, mobile and other device apps, digital systems, and platforms. The lifeblood of these smart devices and systems are algorithms increasingly powered by artificial intelligence (AI). These algorithms make decisions about virtually everything individuals, organisations, and governments do, such as finding the love of our life; recruiting employees; identifying immoral, illegal, and criminal behaviours in individuals and communities; and so on indefinitely. The decisions of these algorithms relate to many core concepts that characterise us humans and our morals, ethics, principles, laws. These algorithms make decisions about our everyday routines that impact—every second or less—innumerable design and process efficiencies, energy usage, planet environment, and individual and national economies. There is an urgent need to develop green AI algorithms, methods, and technologies for smart cities and societies.               

We call for contributions from scientists and engineers to develop green AI algorithms and technologies for smart applications, devices, digital systems, and platforms.

The topics include but are not limited to the development of green AI in the following application domains:

  • Green computing
  • Green data
  • Green communications and networking
  • Green manufacturing and Industry 5.0
  • Green food sciences and technologies
  • Green robotics and cobotics
  • Green land transportation and mobility
  • Green aerospace engineering and transportation
  • Green precision agriculture
  • Green energy
  • Green devices, systems, and platforms
  • Green environmental technologies
  • Green healthcare technologies

Manuscript Submission Information

Manuscripts should be submitted online at by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The many success stories of reinforcement learning (RL) and deep learning (DL) techniques have raised interest in their use for detecting patterns and generating constant profits from financial markets. In this paper, we combine deep reinforcement learning (DRL) with a transformer network to develop a decision transformer architecture for online trading. We use data from the Saudi Stock Exchange (Tadawul), one of the largest liquid stock exchanges globally. Specifically, we use the indices of four firms: Saudi Telecom Company, Al-Rajihi Banking and Investment, Saudi Electricity Company, and Saudi Basic Industries Corporation. To ensure the robustness and risk management of the proposed model, we consider seven reward functions: the Sortino ratio, cumulative returns, annual volatility, omega, the Calmar ratio, max drawdown, and normal reward without any risk adjustments. Our proposed DRL-based model provided the highest average increase in the net worth of Saudi Telecom Company, Saudi Electricity Company, Saudi Basic Industries Corporation, and Al-Rajihi Banking and Investment at 21.54%, 18.54%, 17%, and 19.36%, respectively. The Sortino ratio, cumulative returns, and annual volatility were found to be the best-performing reward functions. This work makes significant contributions to trading regarding long-term investment and profit goals. Full article
