报告题目:智能驾驶汽车三维路径规划方法研究
内容简介:在传统的汽车领域,通常考虑行驶距离来实现二维地图的路径规划方法。本报告研究从三维地图的角度提出应用于智能驾驶汽车的路径规划解决方案。对于三维地形上行驶的汽车,上坡行驶的能耗远大于平路和下坡行驶的能耗,因而,综合考虑行驶距离、能源消耗这两个目标来设计一种三维地图路径规划的代价函数。针对几种路径规划情况,探讨了基于智能优化算法、深度学习算法来分别实现的一些路径规划方案,并在电动汽车和矿用车做了一些仿真验证研究。

报告题目: 欠驱动吊车轨迹规划及非线性控制
内容简介: 吊车具有结构简单、灵活度高、能耗低、重量轻等诸多优点,被广泛应用于建筑业、物流业、冶金业、制造业等领域,其主要任务是将货物“快而准”地搬运至目标位置,并使货物摆动尽可能地小。当前,在实际中应用的吊车大多依赖于人工操作,呈现出效率低、误操作率高、安全系数低、事故率高等诸多不足。对于该类系统,由于系统独立的控制输入个数少于待控自由度,且体现出强非线性特性,其“以少控多”的控制问题具有挑战性,因此其控制研究具有理论与实际的双重重要价值。在本报告中,报告人将汇报近年来在欠驱动吊车系统(桥式吊车、桅杆式吊车、塔式吊车、船用吊车等)的建模、规划、控制等方面取得的一些研究成果,之后将介绍在其它类似机器人系统上进行的一些拓展研究情况。

报告题目:Discrete Bacterial Memetic Evolutionary Algorithms for solving high complexity problems
内容简介:Evolutionary algorithms attempt to copy the solutions nature offers for solving (in the quasi-optimal sense) intractable problems, whose exact mathematical solution is impossible. The prototype of such algorithms is the Genetic Algorithm, which is, however rather slow and often does not find a sufficient solution. Nawa and Furuhashi proposed a more efficient modified one, under the name of Bacterial Evolutionary Algorithm (BEA). Moscato proposed the combination of evolutionary global search with nested local search based on traditional optimization techniques, and called the new approach memetic algorithm (MA).
We attempted to combine BEA first with Levenberg-Marquardt local search and we obtained very good results on a series of benchmarks. The next step was to apply the new type of MA for NP-hard discrete optimization, starting with the classic and well known Traveling Salesman Problem (TSP), applying discrete local search, and thus proposing the novel Discrete Bacterial Memetic Evolutionary Algorithm (DBMEA). Then, we continued with a series of related, but mathematically different graph search problems, applying the same approach. Although we could not improve the tailor made Helsgaun-Lin-Kernighan (HLK) heuristics for the basic TSP, we got comparably good results, and in some other problem cases, we obtained new, so far the best accuracy and running time combinations. The Traveling Repairman Problem is an eminent example, where DBMEA delivers the best solutions.
The advantages of the new approach are as follows:
- Rater general applicability. With minimal adaptation to the concrete problem type the same method could be successfully applied, there was no need to construct new tailor made algorithms for every new problem
- Predictability. Knowing the problem size, it was easy to give a good estimation of the running time, assuming a certain accuracy. This is not true for any of the other approaches, including the HLK, and especially not true for other methods, finding approximate solutions (often with large error)
In the talk, two examples will be presented with standard benchmarks going up to large numbers of graph nodes, and the DBMEA results will be compared with the best practices from the literature. The predictability feature will also be illustrated by a size-running time graph.
