Many of the details of this system are classified and cannot be discussed here. However, it can be stated that the subject system is a man/machine complex, primarily intended for fleet air defense and surface operations and maneuvering. The objectives of the system are: to provide commanders of forces afloat with a broad picture of the current tactical situation; to assist in directing operations in time to intercept and destroy potential threats; and to present the means to coordinate various weapon systems in a combat environment. These are achieved by automating, to a high degree, the collecting, processing, exchanging, and evaluating of large quantities of data through use of computers and digital data processing techniques.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123529183","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}

Time-sharing, in this case, means the simultaneous access to a computer by a large number of independent (and/or related) users and programs. The system is also \"general purpose,\" since there is essentially no restriction on the kind of program that it can accommodate. The system has been used for compiling and debugging programs, conducting research, performing calculations, conducting games, and executing on-line programs using both algebraic and list-processing languages.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127949709","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}

Hopefully, both the weather and recorded information will eventually prove amenable to some form of human control. In the meantime, there must be a continuing effort to achieve balance in the evolution of the concept and equipment aspects of information storage and retrieval (IS&R). It is reasonable to expect overemphasis on equipment capabilities. The emergence of IS&R as a distinct discipline is largely attributable to the significant advances of modern computer technology.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114652824","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}

Each cycle, to be iterated on, consists essentially of two parts: in Part I a \"best\" line is found, in Part II an attempt is made to minimize the given function along this line. Thus, each cycle resembles the corresponding cycle in the method of steepest descent. The method of steepest descent differs from our method in the manner in which in Part I the \"best\" line is found. Steepest descent, in fact, implies that this line (let us call it the \"baseline\" from now on) be defined by the starting point for the cycle and the gradient of the function at this starting point, where the starting point, in turn, is the minimum point of the preceding cycle. Well known modifications of the steepest descent are concerned with, for example, baselines restricted to a subspace normal to the preceding baseline, or with different ways of minimizing along a given baseline, or perhaps with the question as to how feasible it is to seek a minimum at all along a given baseline during each cycle before switching to the next baseline.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134462946","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 those days, the management of programming effort was only slightly different from the management of other types of research activities. Each project was unique and its probability of success uncertain; experience was severely limited; tools and techniques were custom-built for each job. In the computer field today, despite many thousands of man years of experience in program development, we still tend to plan and to manage as if each program were a unique research project. This is partly due to the immaturity of the field, and partly because we have not yet fully recognized that the similarities between computer programs and their development are far more extensive than the differences between them. We have seen the development of many new tools to make the programmer more effective in his work; we must now ask whether we can develop new tools to make the program manager more effective in planning and organizing his scarce resources of talented manpower and expensive computer time.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128052013","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}
