查询词典 hidden line algorithm

With the limitation of the line detection based on traditional Hough transform that the information of the length and the end points of the line is unavailable, a new algorithm which makes use of the accessional strategy based on precognition information is put forward to meet the demand for more information of the line, simulation results show this method is effective.

We must confess that for many years, we were not able to see the hidden meaning of the poem. Two years ago, we were rather intrigued by the line "茂林斧过尽为薪"(line 14). Literally, it means: Lush forests, swept by the axe, completely transformed into firewood. We thought this was a very clever pun because firstly it means that a person without education is transformed through learning into someone useful, as befitting a university. Secondly, Nantah stood on land that was once covered by a rubber estate which had now been cleared to build the university.

老实说，好几年来，我们都没法十分了解此诗隐藏的背景，大概是两年前吧，我们还正在思考此诗中第14行&茂林斧过尽为薪&一句，如果是直译即&利斧把森林砍了，森林就变成薪木&，我们当初以为这句的暗喻是说，正如大学教育一般能把一个无学的人，教育成有用的社会栋梁，正巧南大校址，本来就是一片茂盛胶园，而现今宏立了一所大学，不正是说得极合适，也不就是&茂林斧过尽为薪&吗？

Firstly, after the analysis on probability distribution of GenCos' bidding results, a concept of bid acceptance probability distribution function of GenCos is proposed; then based on the features of bidding structure in day-ahead and real-time markets, a multi-objective bi-level programming bidding strategy model in day-ahead and real-time markets for GenCos is built for electricity markets in which the step-wise bidding function and pay-as-bid settlement protocols are utilized; and then in order to solve the proposed model an algorithm based on Monte Carlo method and genetic algorithm is designed; finally, the simulation of numerical examples are performed to verify the correctness of the proposed model and algorithm.
