Recent advances toward sustainable cities have promoted the concept of near-zero energy consumption. A Positive Energy Building (PEB) model has been developed by the European Union as part of Horizon 2020 to contribute to a cleaner neighborhood environment. To achieve PEB goals, a variety of factors must be optimized, including occupant comfort, building efficiency, economic benefits, and clean energy provision. Building modeling simulation combined with data-driven tools such as machine learning and artificial intelligence can be used to predict energy production and optimize passive and active systems. Based on these findings, this study evaluates studies from the past decade that include data-driven approaches, which accelerate different aspects of PEB, including supply and demand. These aspects include renewable energy supply prediction with the local context, optimizing comfort control with IoT, and reducing demand by optimizing building envelope design, materials selection, and active systems. While there are a few surveys regarding renewable energy management and energy efficiency in buildings, none simultaneously classified the algorithms in a PEB framework. Hence, this work inherently creates a technical framework for future researchers and building engineers to apply the appropriate data-driven approach for achieving net positive energy performance in residential, educational, and commercial buildings. Finally, comparing different applications suggests future research problems that can be addressed by integrating optimization algorithms and machine learning approaches, as well as data gaps that can be resolved to improve prediction accuracy.

Day to day increase in demand of safe and accident free ground vehicle, rapid growth and development of artificial intelligence algorithms and also rapid growth of microelectronics technology are major motives that are driving the development and increased attention of Autonomous Ground Vehicle (AGV) systems. Unstable and non-linear features of AGV need robust control techniques to control the trajectory tracking tasks of the system. Review of related works summery shows that sliding mode controller can handle non-linearity and relatively assure robustness of the system. However;ripple is one of the most common challenge in sliding mode controllers. In this research, Super Twisting Sliding Mode controller (STSMC) is designed to resolve the ripple in sliding mode controller for trajectory tracking control of AGV. Optimal parameters of STSMC controller are tuned using Genetic Algorithm (GA) and Particle Swarm optimization (PSO) technique. To compare the performance of the proposed algorithm, GA tuned Fractional-Order-PID (FOPID) controller is also designed and implemented. Accordingly, STSMC has less (similar to 0.0006 s) tracking error than FOPID controller. The result reveals the outperformance of the proposed algorithm over FOPID controller.

This article is concerned with a recently proposed switching cost aware rounding (SCARP) strategy in the combinatorial integral approximation for mixed-integer optimal control problems (MIOCPs). We consider the case of a control variable that is discrete-valued and distributed on a two-dimensional domain. While the theoretical results from the one-dimensional case directly apply to the multidimensional setting, the structure of the cost function in the graph-based rounding computation is significantly more involved in the two-dimensional case. We describe a set up of the computational graph and the traversal algorithm underlying the SCARP strategy that enable a transfer to the two-dimensional setting. We demonstrate the SCARP strategy in this two-dimensional setting using the example of a MIOCP from topology optimization. We compare the graph-based approach to a ground truth computation using an integer linear programming (ILP) solver. The graph-based approach becomes computationally intractable for medium grid sizes. We show that the one-dimensional SCARP algorithm can be employed on a serialization of the grid cells in these cases and still provides an efficient heuristic that yields superior performance compared with that of other rounding heuristics such as sum-up rounding (SUR).

In protein-ligand docking, an optimization algorithm is used to find the best binding pose of a ligand against a protein target. This algorithm plays a vital role in determining the docking accuracy. To evaluate the relative performance of different optimization algorithms and provide guidance for real applications, we performed a comparative study on six efficient optimization algorithms, containing two evolutionary algorithm (EA)-based optimizers (LGA, DockDE) and four particle swarm optimization (PSO)-based optimizers (SODock, varCPSO, varCPSO-ls, FIPSDock), which were implemented into the protein-ligand docking program AutoDock. We unified the objective functions by applying the same scoring function, and built a new fitness accuracy as the evaluation criterion that incorporates optimization accuracy, robustness, and efficiency. The varCPSO and varCPSO-ls algorithms show high efficiency with fast convergence speed. However, their accuracy is not optimal, as they cannot reach very low energies. SODock has the highest accuracy and robustness. In addition, SODock shows good performance in efficiency when optimizing drug-like ligands with less than ten rotatable bonds. FIPSDock shows excellent robustness and is close to SODock in accuracy and efficiency. In general, the four PSO-based algorithms show superior performance than the two EA-based algorithms, especially for highly flexible ligands. Our method can be regarded as a reference for the validation of new optimization algorithms in protein-ligand docking.
