For the stochastic configuration network (SCN), it randomly produces the hidden parameters and adaptively selects their scopes using an inequality constraint. As a result, the SCN exhibits superior performance in convergence speed and modeling accuracy- low. value and redundant hidden nodes due to the inherent feature of a randomized algorithm. To improve the sparsity of the SCN soft sensor model, a parsimonious stochastic configuration network (PSCN) is proposed in this paper. The L 1 norm is plugged into the cost function of the PSCN, and a new inequality constraint is built to obtain the
This paper studies the problem of spatial path-following control of underactuated autonomous underwater vehicles (AUVs) with multiple uncertainties and input saturation taken into account. Initially, the reduced-order extended state observes (ESOs) is introduced to estimate and compensate all humped uncertainties due to the model parameters perturbations, unmodeled dynamics, environmental disturbances and nonlinear hydrodynamic damping terms. Furthermore, the spatial path-following control strategy is established by combining with backstepping, integral sliding mode control and estimator to
Multimodal multi-objective problems (MMOPs) commonly arise in real-world problems where distant solutions in decision space correspond to very similar objective values. To obtain more Pareto optimal solutions for MMOPs, many multimodal multi-objective evolutionary algorithms (MMEAs) have been proposed. For now, few studies have encompassed most of the recently proposed representative MMEAs and made a comparative comparison. In this study, we first review the related works during the last two decades. Then, we choose 12 stateof-the-art algorithms that utilize different diversity-maintaining
Aiming at the problems of low efficiency of path planning, a new node storage structure is introduced and the search method is optimized to improve the deterministic iterative path planning algorithm. First, the number of antibodies is determined based on the connectable starting path point, when generating the initial antibody with the inspiration of the optimal angle vaccine. Then, the connectable path point of the starting point is treated as the root node to rebuild the new path with path filtering by means of the optimal path fit value. The initial optimal antibody is used as the scree
A chaotic coyote optimization algorithm based on inverse time-decay operator(ICCOA) is proposed to solve the coyote optimization algorithm(COA), such as the poor performance and low diversity. Firstly, the inverse time decay weight factor is added in the process of individual iterative updating, so as to maintain the balance between global search and local development ability and improve the search speed of the algorithm. Secondly, add the chaotic interference mechanism based on Tent chaotic map, some poor individuals in the population were mapped to produce new individuals, thus increasing
