Recent advances in nonequilibrium statistical mechanics have led to a deeper understanding of the thermodynamic cost of computation than that put forth by Landauer and then studied extensively in the computational complexity community. In particular, Landauer's work led to a focus on the number of bit erasures in a computation, due to its relation to the change in entropy between input and output. However new advances in physics|which have been experimentally con rmed|mean we can now calculate additional thermodynamic costs beyond merely the change in entropy between input and output. As a consequence, we now understand that while logically reversible computing can have some thermodynamic bene ts, it is far from the end of the story. The purpose of this paper is to highlight new open questions in computational complexity raised by consideration of these new thermodynamic costs. Beyond leading to a revised viewpoint on the bene ts of logical reversibility, these questions touch on randomized algorithms, average-case complexity, the thermodynamic cost of error correcting codes, and noisy/inexact/approximate computation.
非平衡统计力学的最新进展使人们对计算的热力学代价有了更深入的理解,而不是由兰道尔提出的,然后在计算复杂性领域进行了广泛的研究。特别是,Landauer的工作引起了对计算中比特擦除次数的关注,因为它与输入和输出之间的熵变化有关。然而,物理学的新进展已经被实验证实,这意味着我们现在可以计算额外的热力学成本,而不仅仅是输入和输出之间的熵的变化。因此,我们现在明白,虽然逻辑可逆计算可以有一些热力学上的好处,但它远没有结束。本文的目的是强调由于考虑这些新的热力学成本而引起的计算复杂性的新开放问题。除了导致对逻辑可逆性好处的修正观点之外,这些问题还涉及随机算法,平均情况复杂性,纠错码的热力学成本以及嘈杂/不精确/近似计算。

J. Welch
Blockchains and distributed ledgers, the technologies underlying Bitcoin and other decentralized transaction systems, have been garnering increasing interest in the theoretical distributed comput- ing community. The current column, by Antonio Fernández Anta, Chryssis Georgiou, Kishori Konwar, and Nicolas Nicolaou, starts with an informative overview of the world of distributed ledgers and motivates the need for rigorous approaches. The authors present an approach for formally specifying a distributed ledger in the context of several popular consistency conditions. The authors then give algorithms that implement the di erent variants in message-passing systems subject to crash failures. The article closes with a discussion of intriguing open questions. Many thanks to Antonio, Chryssis, Kishori and Nicolas for their timely contribution!

Review of Network Science by Albert-Làaszlò Barabàasi 网络科学综述Albert-Làaszlò Barabàasi
Pub Date : 2018-06-13 DOI: 10.1145/3232679.3232683
Panos Louridas
Albert-Làaszlò Barabàasi can be credited with bringing network science to the general public. After a series of papers in such heavyweights as Nature and Science, his book Linked gave a popular science account of the field. With Network Science he turns his attention to newcomer students who want to start from scratch and go through a wide ranging, yet accessible, introduction. The explosion of publications and interest in network science makes it easy to forget how new it is. True, the germs of network science were sown many decades back (one can think of the work of Yule and Zipf as early precursors), but it was not until the end of the millennium that scientists from different disciplines, ranging from computer science and mathematics to physics and statistics, started paying attention to what appear to be a set of unifying principles and underlying phenomena. Barabàasi did not invent the field, but his publications created a lot of buzz in many places; and in a short while, scientists all over were studying power laws, critical phenomena, and networks-not computer networks, just networks. (This reviewer remembers the period, when describing a course on network science he had to always add a proviso like "this is not about computer networks"; otherwise students would get the idea that this was about hardcore computer science. The situation has changed somewhat since then.)
Albert-Làaszlò Barabàasi将网络科学带给了大众。在《自然》和《科学》等重量级杂志上发表了一系列论文之后,他的著作《链接》对该领域进行了通俗科学的描述。在《网络科学》一书中,他把注意力转向了那些想从零开始的新学生,并通过广泛而又容易理解的介绍。出版物的爆炸式增长和对网络科学的兴趣使人们很容易忘记它有多新。诚然,网络科学的萌芽早在几十年前就已经播下(人们可以把尤尔和齐夫的工作看作是早期的先驱),但直到本世纪末,来自不同学科的科学家,从计算机科学和数学到物理学和统计学,才开始关注似乎是一套统一的原则和潜在现象。Barabàasi并不是这个领域的发明人,但他的出版物在很多地方引起了轰动;在很短的时间内,全世界的科学家都在研究幂律、关键现象和网络——不是计算机网络,只是网络。(笔者还记得有一段时间,在描述一门网络科学课程时,他总是不得不加上一个附带条件,比如“这不是关于计算机网络的”;否则学生们会认为这是关于硬核计算机科学的。从那以后,情况有所改变。)

W. Gasarch
There have been two polls asking theorists (and others) what they thought of P vs NP (and other questions) [4, 5]. Both were written by William Gasarch and appeared in the Complexity Column of SIGACT News, edited by Lane A. Hemaspaandra. They were in 2002 and 2012. Since William Gasarch is fond of Van der Waerden's theorem, you would think the next poll would be 2022; however, Lane asked if it could be a bit earlier so as to be the 100th issue of his column. So here we are. In the past the questions for the poll appeared in Lane's column. This time they appear here in the Open Problems Column, which makes sense since, well, P vs NP is indeed an open problem.
有两个民意调查询问理论家(和其他人)他们对P vs NP(以及其他问题)的看法[4,5]。这两篇文章都是由William Gasarch撰写的,发表在SIGACT News的复杂性专栏上,由Lane A. Hemaspaandra编辑。分别是2002年和2012年。既然威廉·加萨奇(William Gasarch)喜欢范德华登定理(Van der Waerden’s theorem),你可能会认为下一次投票将在2022年;然而,莱恩问他是否可以早一点,这样他的专栏就可以第100期了。所以我们在这里。过去,民意调查的问题出现在莱恩的专栏中。这次它们出现在开放问题专栏中,这是有意义的,因为P对NP确实是一个开放问题。

Social choice theory is an area of economics that studies collective decision making. Examples of collective decision making include sharing a cake or a resource among a group of people or friends, tallying votes in an election, and aggregating opinions of various experts. Computational social choice is a discipline which may be considered to be at the intersection of economics and computer science. This book deals with recent trends related to computational aspects of collective decision making. It contains contributions of experts in computational social choice. The book is divided into three parts that focus on scenarios, techniques, and applications, respectively. It has been published as a sequel to the Handbook of Computational Social Choice, Cambridge University Press, 2016, recently reviewed by me in this column (SIGACT News 48(4), December 2017, pp. 13-17). Ulle Endriss, the editor of this book, was also an editor of the Handbook. This book has been published by AI Access, a not-for-profit publisher. It is available for free online at the URL http://research.illc.uva.nl/COST-IC1205/Book/, and the hard copy is very nominally priced. The book's publication

Review of Words and Graphs by Sergey Kitaev and Vadim Lozin Sergey Kitaev和Vadim Lozin的《词汇与图表》书评

Two distinct letters x and y in a word alternate if, after deleting all other letters in the word, the resulting word is of the form xyxy : : : or yxyx : : : . A graph G = (V;E) is word-representable if there exists a word w over the alphabet V such that the letters x and y alternate in w if and only if there is an edge connecting x and y in G. If graphs can be represented by words then exciting new possibilities arise for investigating graph properties in terms of the properties of the words that represent them. In addition, words (i.e. strings) would offer an additional way of storing and manipulating graph structures in computation. This textbook is a comprehensive survey of word-representable graphs and the relationships between combinatorics on words and graph properties. The contents are accessible to graph theorists, formal language theorists, computer scientists, and students who have some familiarity with graph theory and words.
如果在删除单词中的所有其他字母后,生成的单词的形式为xyxy:::或yxyx:::,则单词中的两个不同的字母x和y交替出现。图G = (V;E)是词可表示的,如果在字母V上存在一个单词w,使得字母x和y在w中交替存在,当且仅当在G中有一条边连接x和y。如果图可以用词来表示,那么根据表示图的词的性质来研究图的性质就会出现令人兴奋的新可能性。此外,单词(即字符串)将提供一种在计算中存储和操作图结构的额外方式。这本教科书是一个全面的调查字可表示的图和组合之间的关系,在词和图的性质。图论学家、形式语言理论家、计算机科学家以及对图论和词汇有一定了解的学生都可以访问本书的内容。

A graph G = (V;E) is word-representable if there exists a word w over the alphabet V such that the letters x and y alternate in w if and only if there is an edge connecting x and y in G. If graphs can be represented by words then exciting new possibilities arise for investigating graph properties in terms of the properties of the words that represent them. In addition, words (i.e. strings) would offer an additional way of storing and manipulating graph structures in computation. This textbook is a comprehensive survey of word-representable graphs and the relationships between combinatorics on words and graph properties. The contents are accessible to graph theorists, formal language theorists, computer scientists, and students who have some familiarity with graph theory and words.","PeriodicalId":22106,"journal":{"name":"SIGACT News","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79985567","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}

In his Disquisitiones Arithmeticæ, quoted above, Gauss called it the “fundamental theorem” that “must certainly be regarded as one of the most elegant of its type.”5 In private, he dubbed it the “Theorema Aureum,” the “Golden Theorem.” The law itself, its many proofs, its implications and generalizations, its influence on the advancement of number theory, and the underlying history, are deep and fascinating.
在上面引用的《算术研究》中,高斯称其为“基本定理”,“当然必须被视为同类定理中最优雅的定理之一”。私下里,他称之为“金色定理”。这个定律本身,它的许多证明,它的含义和概括,它对数论发展的影响,以及潜在的历史,都是深刻而迷人的。
