Trajectory optimizationMotion planningLinear temporal logicWe address the problem of optimal trajectory planning for a fixed wing- or quadrotor aircraft to satisfy linear temporal logic (LTL) specifications on its motion. To this end, we propose a randomized sampling-based motion planning algorithm with...
通常,在RRT*中,我们的新轨迹如果无法通过碰撞检测,就会将新轨迹剪枝了,但是这里则进行进一步优化。也就是我们所说的regional optimization: 他考虑三项惩罚项: smoothness term: \begin{aligned} J_{s} &=\int_{0}^{T}\left[p^{(3)}(t)\right]^{2} d t \\ &=\sum_{i=1}^{j} \mathbf{c}_{...

The problem of query execution time prediction and query optimization is fundamental in database systems. Although decades of research has been devoted to this area and significant progress has been made, it remains a challenging problem for many queries in real-world database workloads. 关键词: ...
Abstract This paper surveys the use of Monte Carlo sampling-based methods for stochastic optimization problems. Such methods are required when—as it often happens in practice—the model involves quantities such as expectations and probabilities that cannot be evaluated exactly. While estimation procedures...
The whale optimization algorithm (WOA) has shown promise in addressing this challenge, but issues persist, including poor stability, low efficiency, and accuracy in COVID-19 threshold image segmentation. To tackle these issues, we introduce a Latin hypercube sampling initialization-based multi-strategy...

the performance of the swarm intelligence optimization algorithm can significantly affect the efficiency and results of image segmentation13, so further optimization of the algorithm is needed to adapt and solve the optimization problems on different segmentation tasks when the algorithm is applied to the...
In order to determine the winners of the auction, they need to solve a combinatorial optimization problem known as winner determination problem (WDP). In practice, shippers must resolve the WDP under shipment volume uncertainty due to limited information of future demands. In this paper, we ...
