The Impact of Object Immutability on the Java Class Size

P. 1868-1872.

Zykov S. V., Bugayenko Y.

According to the subjective opinions of many industry experts, object immutability is a virtue in object-oriented programming, since it leads to side-effect-free design, cleaner code, better concurrency, and many other factors. However, it has never been empirically demonstrated exactly how immutability affects quality metrics of object-oriented programs. In the following research, we analyzed 97508 classes from 240 public Java repositories to find out how immutability affects the size of the code.

Proceedings of the International Workshop CS&P'2013

Edited by: M. Szczuka, L. Czaja, M. Kacprzak. Vol. 1032. Bialystok: Bialystok University of Technology, 2013.

This volume contains the Proceedings of 22nd Concurrency, Specification and Programming (GS&P) Workshop held on September 25-27, 2013 in Warsaw. There were 48 submissions. Each submission was reviewed by two program committee members. The committee decided to accept 40 papers. The Workshop was initiated in the mid 1970s by computer scientists and mathematicians from Warsaw and Humboldt Universities, as Polish-German annual meetings. They were suspended for some years in the 1980s and reactimed in 1992. Thereafter, the Workshop, organised alternatingly by the Institutes of Informatics and Mathematics of the University of Warsaw and the Institute of Informatics of Humboldt University in Berlin on the basis of an exchange program, has been given the name GS&P. It should be mentioned that the CS&P meetings, initially purely bilateral, since 1992 have developed into events attended by participants from a number of different countries beside Poland and Germany. The present GS&P'13 meeting attracted contributors from: Canada, Egypt, France, Germany, Italy, Nepal, The Netherlands, Poland, Russia, Serbia, Slenakia, Sweden, Turkey, United Kingdom, United States, and Vietnam. The organisation of this year's CS&P would not be possible without the resources and financing provided by seven institutions. We would like to thank the Faculty of Mathematics, Informatics and Mechanics of the University of Warsaw and the Institute of Informatics of the Humboldt University of Berlin for the continuing financial and organisational support provided to GS&P over last twenty-two years. The essential financial backing received from the Warsaw Center of Mathematics and Computer Science made the organisation of CS&P 2013 possible. Our thanks go to the Bialystok University of Technology for providing the means for publishing this proceedings volume. Last, but not the least, we are grateful for the significant financial support provided by the Vistula University in Warsaw.

Объектно-атрибутный подход для реализации систем искусственного интеллекта

Салибекян С. М., Панфилов П. Б. Нейрокомпьютеры: разработка, применение. 2011. № 11. С. 9-17.

A new computer architecture named object-attribute is offered in the article. Computer of the architecture have all necessary properties for Artificial Intelligence: abstraction of data and program, height concurrency, isomorphism of data and program (i.e. possibility of painless changing of program and data structures), training and self-training of computer system, dataflow, integration of data and program, generation of object description from simple description to complex description, implementation of distribute computer system.

Concurrency, Specification and Programming. CS&P 2014. Proceedings of the 23th International Workshop on Concurrency, Specification and Programming. Chemnitz, Germany, September 29 - October 1, 2014.

Edited by: L. Popova-Zeugmann. Vol. 1269: CEUR Workshop Proceedings (CEUR-WS.org). Berlin: Humboldt University of Berlin, 2014.

This volume contains the papers presented at CS&P 2014: 23th International Workshop on Concurrency, Specification and Programming held on September 28 - October 1, 2014 in Chemnitz. Since the early seventies Warsaw University and Humboldt-University have alternately organized an annual workshop - since 1993 as CS&P. Over time, it has grown from a bilateral seminar to a meeting attended also by colleagues from other countries than Poland and Germany. This year there are 34 participants from 10 countries.

О непреднамеренном нарушении принципа инкапсуляции при разработке объектно-ориентированных программ

Кириченко А. А. В кн.: Инновационные информационные технологии: Материалы международной научно-практической конференции. Т. 1. М.: МИЭМ НИУ ВШЭ, 2013. С. 479-488.

When training in programming computer testing of students shows satisfactory knowledge of the principles of object-oriented programming. But in the course of performance some difficult programs (homeworks, term papers) the majority of them breaks the principle of encapsulation. In article the reasons of inadvertent violation by students of the principle of encapsulation and possible ways of their elimination are considered.
