During the optimization process, producing high-quality individuals is always the goal of evolutionary algorithms. So, how can we generate such promising offspring individuals? The key lies in an optimizer with the potential to consistently produce superior individuals. However, designing the operator with learning ability in an optimizer has not been well explored in the existing research. To overcome this drawback, a learnable competition operator driven by reinforcement learning (RL) technique is proposed to generate high-quality individuals and further improve the performance of the algorithm. First, with the help of Q-learning, a classical RL technique, the size of elite particle set in the population is taken as the set of action, each elite particle corresponds to a action. The optimal action is considered to be the next state. Then, a three-dimensional Q-table is designed for the whole population, so that each particle can learn its elite particles, rather than randomly selecting elite particles to guide the particle's evolution process. Furthermore, a novel algorithm embedded with the learnable competition operator is proposed. Finally, compared with the other state-of-the-art algorithms, the experimental results demonstrate that the proposed algorithm significantly enhances the solution accuracy.

Advanced building energy system controls, such as model predictive control, rely on accurate system models. To reduce the modelling effort in the building sector, data-driven models are becoming increasingly popular in research. Despite their promising performance, data-driven models are considered black boxes. This black box nature is an obstacle to widespread application, as it is difficult for building operators to understand how predictions are made. Concepts known as Explainable Artificial Intelligence are being developed to improve the interpretability of black box models. This work combines the popular Explainable Artificial Intelligence method Shapley Additive Explanations (SHAP) with data-driven model predictive control to increase the interpretability of artificial neural networks used as process models during model creation. Using a standardised residual building energy system for controller testing, an in-depth analysis of how the models make predictions is carried out. In addition, the influence of different model setups on the control performance is evaluated. The results show that the different control performances can be justified by analysing the underlying models with SHAP. SHAP shows how the characteristics of a feature affect the prediction and reveals weaknesses in the model. In addition, the features can be sorted according to their influence on the prediction, which is utilized for feature selection.

A major challenge in autonomous flights is unknown disturbances, which can jeopardize safety and cause collisions, especially in obstacle-rich environments. This letter presents a disturbance-aware motion planning and control framework for autonomous aerial flights. The framework is composed of two key components: a disturbance-aware motion planner and a tracking controller. The motion planner consists of a predictive control scheme and an online-adapted learned disturbance model. The tracking controller, developed using contraction control methods, ensures safety bounds on the quadrotor's behavior near obstacles with respect to the motion plan. The algorithm is tested in simulations with a quadrotor facing strong crosswind and ground-induced disturbances.
