Summary: In this article, an optimization-based framework for multicopter trajectory planning under geometrical configuration constraints and user-defined dynamic constraints is presented. The framework utilizes a novel trajectory representation based on optimality conditions for control effort minimization. Linear-complexity operations are designed to achieve spatial-temporal deformation for different planning requirements. The framework supports the elimination of geometrical constraints through smooth maps, and is able to handle a variety of state-input constraints through decoupling and backward differentiation. The framework transforms a generally constrained multicopter planning problem into an unconstrained optimization, resulting in reliable and efficient solutions.

Summary: The emerging field of soft robotics presents a new paradigm for robot design where precision through rigidity is replaced by cognition through compliance. Soft robots, like octopuses, have flexible bodies that can interact with fragile objects and navigate unstructured environments. Currently, the lack of efficient modeling tools means soft robots are primarily designed by hand, but autonomous design methodologies are urgently required for high-performing robots.

Summary: In this work, an improved Whale Optimization Algorithm (QGBWOA) is proposed to address the problems of falling into local optimum and slow convergence. Quasi-opposition-based learning and Gaussian barebone mechanism are introduced to enhance the searching ability and diversity of WOA. Experimental results on benchmark datasets demonstrate the significantly improved convergence accuracy and speed of QGBWOA. Furthermore, applications in feature selection and multi-threshold image segmentation validate its capability in solving complex real-world problems.
