Steiner tree problem belongs to combinatorial optimization discipline and is NP-hard problem. Over the past three centuries, many mathematicians have extended and extended this problem, making the steiner tree tree problem further developed. This paper mainly deals with a sub-problem of steiner tree, the Minimum Rectilinear Steiner tree problem. In this paper, based on dynamic programming, a classical technique to solve the steiner tree problem, two algorithms, L-MRST and Z-MRST, are proposed to construct the Minimum Rectilinear Steiner tree on a plane. Both algorithms use point data discretization for pre-tree preparation. However, in the same solution mode, the algorithm l-mrst directly iterates on the current subtree to build the final tree. The algorithm zmrst preprocesses the feasible z-layout standby of all points and enumerates all possible layouts when traversing the nodes. This algorithm increases the algorithm complexity, but the results are obviously optimized. Experimental results also bear this out. For the Minimum Rectilinear Steiner tree problem, the two algorithms in this paper have their own advantages and disadvantages, which can help VLSI problem to some extent, and can effectively optimize the large-scale wire network routing problem.","PeriodicalId":188256,"journal":{"name":"Proceedings of the 8th EAI International Conference on Green Energy and Networking, GreeNets 2021, June 6-7, 2021, Dalian, People’s Republic of China","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130319226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the lack of optical coherence, the essence of optical fiber communication is a noise carrier communication system. In order to be able to communicate with high capacity over long distance, various modulation methods and heterodyne reception are used to construct coherent optical communication system. Heterodyne/coherent fiber communication is being accelerated in its research and development due to the possibility of increasing the receiving sensitivity by 20-30dB[1]. The coherent optical communication system has good selectivity and large communication capacity. The receiving sensitivity of the coherent balanced detection technology is about 10 dB ~ 20 dB higher than that of the incoherent optical communication system, which greatly extends the transmission distance [2]. This paper will study the optical coherence communication system and its simulation, the main components are as follows: 1. General information and importance of the development status and future trend of coherent optical communication. 2. A review of coherent optical communication system. 3. Based on the understanding and analysis of the previous chapter, the OptiSystem software platform is used for system simulation.

Between the CT imaging terminal and the post-image 3D reconstruction processing terminal, there is a massive amount of image data for transmission, and the process requires a lot of transmission time, which is challenging to meet the characteristics of large-scale and high-throughput research. Today’s medical transmission bus Technology does not meet the low cost and high convenience of future plant phenotype research. For large-scale population genetic analysis after the three-dimensional phenotype of plant roots, such as quantitative trait locus mapping (QTL) research, it is necessary to have high the technology of flux image data transmission is added based on the three-dimensional analysis of root system. In this paper, under the conditions of underground soil, a high-throughput visual light image transmission system for X-CT plant root CT scanning imager is proposed. It uses the characteristics of fast data transmission speed and large throughput of visible light, and image transmission can be useful. Reduce the time of image data transmission between the upper imaging terminal and the lower image processing terminal and reduce the later 3D reconstruction research time cost.","PeriodicalId":188256,"journal":{"name":"Proceedings of the 8th EAI International Conference on Green Energy and Networking, GreeNets 2021, June 6-7, 2021, Dalian, People’s Republic of China","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127300209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at the problem of the secure transmission of image information in the network, an image encryption algorithm based on laser chaotic system and neural network is designed in this work. The phase diagram, Lyapunov exponential spectrum and bifurcation diagram analysis confirmed the chaotic characteristics of the single-mode laser power system. On this basis, the plaintext image is first compressed by the BP neural network, and then the compressed image is chaotically generated and diffused using the chaotic sequence obtained by the single-mode laser chaotic system to obtain the ciphertext image, and finally the histogram, Adjacent pixel correlation, anti-differential attack, information entropy and other aspects to test the security of the proposed encryption scheme.
