  • TOM-DOC V3.2A Has the Following New Features: Support of NK2/4 Disks for the Internal Work Files
    Introduction 1 Introduction 1.1 Product Characteristics TOM-DOC edits texts as ready-to-print documents based on commands entered with the text. Editing functions include automatic classification of a text into chapters, sub- chapters, sections, etc., line and page breaks, automatic hyphenation in a number of national languages and automatic generation of table of contents and keyword index. TOM-DOC is particularly well suited for producing documents required for development projects, such as studies, specifications, performance descriptions and manuals. TOM-DOC can be used directly as a separate program or interactively together with the product TOM-TI. When TOM-DOC is called directly, the TOM-DOC texts already entered using the BS2000 editor $EDT are read from system input and the edited result is written to the SYSLST system file. In interactive mode, the texts are entered and modified in the TOM-TI editor and formatted as documents using TOM-DOC. The original text and the formatted document can be displayed at the same time in different windows of the editor. TOM-DOC (SINIX), which is largely compatible with TOM-DOC (BS2000), is available on the SINIX platform. This means that text files can be created and/or edited under either BS2000 or SINIX. TOM-DOC (SINIX) is part of SoftBench-LNK and works with the MAXed/XM (SINIX) editor.

  • Monte-Carlo Tree Search Using Expert Knowledge: an Application to Computer Go and Human Genetics
    Curso 2012/13 CIENCIAS Y TECNOLOGÍAS/23 I.S.B.N.: 978-84-15910-90-9 SANTIAGO BASALDÚA LEMARCHAND Monte-Carlo tree search using expert knowledge: an application to computer go and human genetics Directores J. MARCOS MORENO VEGA CARLOS A. FLORES INFANTE SOPORTES AUDIOVISUALES E INFORMÁTICOS Serie Tesis Doctorales ciencias 23 (Santiago Basaldúa Lemarchand).indd 1 18/02/2014 11:24:43 Universidad de La Laguna Abstract Monte-Carlo Tree Search Using Expert Knowledge: An Application to Computer Go and Human Genetics During the years in which the research described in this PhD dissertation was done, Monte-Carlo Tree Search has become the preeminent algorithm in many AI and computer science fields. This dissertation analyzes how expert knowledge and also online learned knowledge can be used to enhance the search. The work describes two different implementations: as a two player search in computer go and as an optimization method in human genetics. It is established that in large problems MCTS has to be combined with domain specific or online learned knowledge to improve its strength. This work analyzes different successful ideas about how to do it, the resulting findings and their implications, hence improving our insight of MCTS. The main contributions to the field are: an analytical mathematical model improving the understanding of simulations, a problem definition and a framework including code and data to compare algorithms in human genetics and three successful implementations: in the field of 19x19 go openings named M-eval, in the field of learning playouts and in the field of genetic etiology. Also, an open source integer representation of proportions as Win/Loss States (WLS), a negative result in the field of playouts, an unexpected finding of a possible problem in optimization and further insight on the limitations of MCTS are worth mentioning.
