ACM Transactions on Algorithms welcomes submissions of original research of the highest quality dealing with algorithms that are inherently discrete and finite, and having mathematical content in a natural way, either in the objective or in the analysis. Most welcome are new algorithms and data structures, new and improved analyses, and complexity results. Specific areas of computation covered by the journal include * combinatorial searches and objects; * counting; * discrete optimization and approximation; * randomization; * parallel and distributed computation; * algorithms for * graphs, * geometry, * arithmetic, * number theory, * strings; * on-line analysis; * cryptography; * coding; * data compression; * learning algorithms; * methods of algorithmic analysis; * discrete algorithms for application areas such as * biology, * economics, * game theory, * communication, * computer systems and architecture, * hardware design, * scientific computing This area list will evolve as the research community explores new areas. In addition to original research articles TALG will include special features appearing from time to time such as invited columns and a problems section.

Individual articles published in ACM Transactions on Applied Perception are available through the Article Express International FAX service. If you wish to search for specific articles, go to our Past Issues. Note that abstracts for many of the articles are available online, and ACM TAP subscribers may download electronic versions of the latest articles.

The ACM Transactions on Architecture and Code Optimization focuses on hardware, software, and system research spanning the fields of computer architecture and code optimization. Articles that appear in TACO present new techniques and concepts or report on experiences and experiments with actual systems. Insights useful to architects, hardware or software developers, designers, builders, and are emphasized.

ACM Transactions on Autonomous and Adaptive Systems (TAAS) is a venue for high quality research contributions addressing foundational, engineering, and technological aspects of computing systems exhibiting emergent and adaptive behaviour. TAAS encourages contributions aimed at supporting the understanding, development, and control of such systems based on sound theoretical models, including but not limited to bio-inspired models. ACM TAAS spans complexity, self-adaptation, autonomic computing, and multi-agent systems. It addresses research being undertaken by an interdisciplinary research computing community -- and provide a common platform under which this work can be published and disseminated. Such a common view would consider macro-behavior of decentralized applications emerging from micro-behavior of its autonomous, possibly mobile components.

For the purposes of TOCL, the field of computational logic consists of all uses of logic in computer science. This area has a great tradition in computer science. Several researchers who earned the ACM Turing award have also contributed to this field, namely Edgar Codd (relational database systems), Stephen Cook (complexity of logical theories), Edsger W. Dijkstra, Robert W. Floyd, Tony Hoare, Amir Pnueli, and Dana Scott (program logics, program derivation and verification, programming languages semantics), Robin Milner (interactive theorem proving, concurrency calculi, and functional programming), and John McCarthy (functional programming and logics in AI).

The purpose of ACM Transactions on Computer Systems is to present research and development results on the design, specification, realization, behavior, and use of computer systems. The term "computer systems" is interpreted broadly and includes systems architectures, operating systems, distributed systems, and computer networks. Articles that appear in TOCS will tend either to present new techniques and concepts or to report on experiences and experiments with actual systems. Insights useful to system designers, builders, and users will be emphasized. Among the topics within the scope of TOCS are the following: design of entire systemstechnology shiftsengineering trade-offsstorage managementsystem-user interfacecommunication managementreliabilityimplementation techniquessystem validationperformance models design of system componentsprocessor managementsecurityfile systemsprotocolsdata organizationfault toleranceinformation flowsystem verificationperformance analysisIt is possible that a TOCS paper of interest to a large segment of the computing community would be published in Communications in order to keep the general ACM membership apprised of developments in the systems area. TOCS publishes research and technical papers, both short and long. It includes technical correspondence to permit commentary on technical topics and on previously published papers.

This ACM Transaction seeks to be the premier archival journal in the multidisciplinary field of human-computer interaction. Since its first issue in March 1994, it has presented work of the highest scientific quality that contributes to the practice in the present and future. The primary emphasis is on results of broad application, but the journal considers original work focused on specific domains, on special requirements, on ethical issues -- the full range of design, development, and use of interactive systems.

The ACM Transactions on Database Systems (TODS) publishes original archival papers in the area of databases and closely related disciplines. The majority of the papers that have appeared in TODS address the logical and technical foundation of data management.The international Editorial Board is composed of recognized experts in the various subareas of this field, all with a commitment to maintain TODS as the premier publication in this active field. Papers can be submitted directly to any of the editors. The Editorial Board maintains contact with ACM's Special Interest Group on Management and Organization of Data (SIGMOD), as well as with other societies, to encourage submittal of advanced and original papers. When appropriate, concise results may be submitted as technical notes; technical comments on earlier publications are welcome as well.

A special issue serves several purposes: it provides a well-defined location for papers that relate to a common theme; it can serve as a catalyst for an emerging field by providing that highly-visible forum for the topic; and it encourages authors to submit high-quality work by providing them with a focused review process and publication schedule. TECS is committed to providing adequate space to regular submissions to the transactions, but TECS is also happy to provide room for special issues of interest to the embedded systems community.A special issue may be instigated by the TECS editorial staff or may be proposed by potential guest editor(s). The special issue associate editor works with the TECS editorial staff to refine the special issue's call for papers and set a timetable for submission and review. The call for papers is then publicized through a variety of mechanisms: notices in TECS and other publications, Web sites, flyers at conferences etc.Authors submit their special issue contributions to the TECS Web site. Authors must be sure to use the Web site's mechanism to mark the contribution as a special issue submission; as a safety measure, authors should also put the special issue name on the first page of the submission.Submissions to the special issue must be accepted on the first round of review; the special issue associate editor may request minor changes to the paper before publication. Since journal articles typically go through two rounds of review before publication, the special issue process offers quick archival publication for papers that meet the highest standards.

As illustrated below, the TOG journal has a strong synergy with ACM SIGGRAPH, the premiere conference organization in graphics. Of the six issues published by TOG each year, two are special issues containing the papers presented at the annual SIGGRAPH and SIGGRAPH Asia conferences. Conversely, authors of papers published in the regular issues of TOG can present their work at either of these two conferences. Also, several paths provide reviewer continuity between the conference and the journal.

ACM Transactions on Information Systems (TOIS) is a scholarly journal that publishes the highest quality papers about the design and evaluation of computer software that helps people find, organize, analyze, and use information in a variety of media. TOIS is published quarterly.

ACM, the world’s largest educational and scientific computing society, delivers resources that advance computing as a science and a profession. ACM provides the computing field's premier Digital Library and serves its members and the computing profession with leading-edge publications, conferences, and career resources.
