Special Issue Information

Dear Colleagues,

Humanity's problems are becoming increasingly complex on a daily basis, and approaches that hybridize different techniques have been critical to solving many of these problems. Artificial intelligence (machine learning, deep learning, reinforcement learning, expert systems, and fuzzy systems) and metaheuristics (genetic algorithms, memetic algorithms, swarm intelligence, and differential evolution, among others) are two important examples of fields of knowledge that can be synergistically combined to solve highly complex problems.

In this Special Issue, we are interested in recent solutions that explicitly show the interrelation of these two fields (AI and metaheuristics) for the solution of academic, scientific, or industrial problems where, in addition, it is evident how the proposed solution was subjected to an evaluation concerning the quality of the obtained solution, the execution time, or other relevant metrics. Topics include, but are not limited to, the following:

  • Hybrid intelligent optimization techniques for solving very high-complexity problems.
  • Applications in industry, transportation, health, agriculture, services, and others.
  • Metaheuristic algorithms enhanced with artificial intelligence techniques and vice versa.

The traditional Simultaneous Localization and Mapping (SLAM) systems are based on the strong static assumption, and their performance will degrade significantly due to the presence of dynamic objects located in dynamic environments. To decrease the effects of the dynamic objects, based on the ORB-SLAM2 system, a novel dynamic semantic SLAM system called MOR-SLAM is presented using a mask repair method, which can accurately detect dynamic objects and realize high-precision positioning and tracking of the system in dynamic indoor environments. First, an instance segmentation module is added to the front end of ORB-SLAM2 to distinguish dynamic and static objects in the environment and obtain a preliminary mask. Next, to overcome the under-segmentation problem in instance segmentation, a new mask inpainting model is proposed to ensure that the integrity of object masks, which repairs large objects and small objects in the image with the depth value fusion method and morphological method, respectively. Then, a reliable basic matrix can be obtained based on the above-repaired mask. Finally, the potential dynamic feature points in the environment are detected and removed through the reliable basic matrix, and the remaining static feature points are input into the tracking module of the system to realize the high-precision positioning and tracking in dynamic environments. The experiments on the public TUM dataset show that, compared with ORB-SLAM2, the MOR-SLAM improves the absolute trajectory accuracy by 95.55%. In addition, compared with DynaSLAM and DS-SLAM on the high-dynamic sequences (fr3/w/rpy and fr3/w/static), the MOR-SLAM improves the absolute trajectory accuracy by 15.20% and 59.71%, respectively.

This paper introduces a new approach to controlling Pressure Swing Adsorption (PSA) using a neural network controller based on a Model Predictive Control (MPC) process. We use a Hammerstein–Wiener (HW) model representing the real PSA process data. Then, we design an MPC-controlled model based on the HW model to maintain the bioethanol purity near 99% molar fraction. This work proposes an Artificial Neural Network (ANN) that captures the dynamics of the PSA model controlled by the MPC strategy. Both controllers are validated using the HW model of the PSA process, showing great performance and robustness against disturbances. The results show that we can follow the desired trajectory and attenuate disturbances, achieving the purity of bioethanol at a molar fraction value of 0.99 using the ANN based on the MPC strategy with 94% of fit in the control signal and a 97% fit in the purity signal, so we can conclude that our ANN can be used to attenuate disturbances and maintain purity in the PSA process.
