Prehistory

What today is the present is history tomorrow. From the perspective of time, events that seemed extremely important in their time fade away, no longer seem so important. For this reason, even scholarly books written by great historians lose their relevance over time and become the basis for other history books.

October 1, 1956, is a very important date for science in Lithuania. That is a formal date of the emergence of many scientific trends in Lithuania. This is the date that the Physical and Technical Institute was liquidated and three new institutes were established on its basis: the trends of scientific research were confirmed. One of those institutes was the Institute of Physics and Mathematics. It was then that the word MATHEMATICS appeared in the title of the institute. Over the years, the Institute of Physics and Mathematics has been reorganized and renamed several times, but it has never lost the word "mathematics" in its name or the mathematical trend in its research. Therefore the date of foundation of the present Institute of Mathematics and Informatics is to be considered October 1, 1956.

1956-1966 Institute of Physics and Mathematics before the first reorganization

1 October 1956 past kosc627x400 1Foundation of the Institute of Physics and Mathematics (IPhM) Director Academician of the Lithuanian Academy of Sciences Prof. Adolfas Jucys, deputy director Dr. Jonas Kubilius, deputy director for farm affairs – Petras Česnulevičius.
After the reorganization of the Physico-technical Institute, three institutes have been established.
IPhM was situated on Kosciuskos st. 30, it occupied 143 m2 area, it had 24 staff workers and 10 vacancies.
The Institute was comprised of 3 subdivisions that have developed into independent institutes over time:
  • Mathematical sector (MS) that has grown into the present Institute of Data Science and Digital Technologies. The Head of the sector was Dr. Jonas Kubilius. He also was a deputy director for scientific matters of the institute.
  • Theoretical Physics sector (head Prof. A.Jucys) has developed into 2 institutes - the Institute of Theoretical Physics and Astronomy and the Institute of Physics.
  • Semiconductor laboratory (head Prof. Povilas Brazdžiūnas) that has grown into the Institute of Semiconductor Physics.

sc senas645x400
The building of the Computer Centre (CC) was started in Vilnius, Lentpjuvių st. 7 (now A. Gostauto st. 12).
Director of the Institute of Physics and Mathematics, Academician Adolfas Jucys put much effort to acquire and use computing equipment. There were some preparations to acquire an electronic computing machine.
1 May 1961

zukauskas198x294Dr. Kostas ŽukauskasThe Electronic Computing Machine laboratory (ECML) was established, headed by Dr. Kostas Žukauskas.
Since 1955 Acad. Adolfas Jucys has been looking for scientific institutions that could prepare specialists for Lithuania to work in the fields of computer science. In the spring of 1957, physicists-theoreticians Ivanas Glembockis and Kostas Žukauskas left for the Computer Centre of the USSR Academy of Sciences to work on probation there. K. Žukauskas was studying the structure of electronic computing machines. Later on, Kostas Žukauskas explored the structure of a computing machine BESM at the Institute of Fine Mechanics and Computing Technique of the USSR Academy of Sciences as well as the structure of a specialized analog-code converter at the Institute of Engineer Physics (Moscow). Later on, the knowledge was applied in designing an analog-code converter for the electronic computing machine BESM-2M of the Lithuanian Academy of Sciences.
14 July 1962

esm besm 2 627x400The first large-scale electronic computing machine BESM-2M was put into action.

The RAM of BESM was 2047 words by 39 bits each, it had two magnetic drums (MD) with 12290 words in each, and two devices of magnetic tapes containing 131000 words each. The computer consisted of 3000 electronic lamps and 10000 diodes, and it consumed 43 KW of electric power. Computation algorithms were written (programmed) in computer codes. Only 50% of its work time was effective, and the rest time was spared for fault avoidance and repairs.
1 October 1962

matulis1 300x436

The Computational Mathematics sector (CMS) was set up, headed by Dr. Vilius Matulis.
The establishment of this sector reflected a new qualitative jump in the history of IPhM as well as of the whole Lithuanian Academy of Sciences: the beginning of computation technology science research (presently-informatics). 
6 December 1962 Dr. Vytautas Statulevičius was nominated a deputy director for scientific work of the Institute of Physics and Mathematics (IPhM), remaining concurrently the head of the Mathematical Sector (MS).
10 October 1963

pozela1 300x434

Prof. Juras Požela was elected director of the Institute of Physics and Mathematics (IPhM).
1964 The building of the Computer Centre (CC) was completed in Vilnius, Lentpjuvių st. 7 (now A. Gostauto st. 12). Construction of the premises was accomplished when the first computing machine was operating.
1 July 1964

The Technical Cybernetics sector (TCS) was established. Head Dr. Kostas Žukauskas.
Jonas Petkevičius was appointed the head of The Electronic Computing Machine Laboratory (ECML).
Dr. Eduardas Vilkas was appointed the head of the Computational Mathematics sector (CMS). This was due to the reorganization of CMS:

  • A group of employees working in mathematical logic and algorithms and programming theory were transferred to the Mathematical Logic and Programming Sector (MLPS).
  • The rest of the staff was joined by another group of gaming theory workers.

The Mathematical Logic and Programming sector (MLPS) was set up. Dr. Vilius Matulis became the head of the MLPS.

9 February 1965

The Mathematical sector (MS) was named a Probability Theory sector (PTS). Dr. V.Statulevičius remained its head. This name could better reflect the scientific research trends of the Mathematical sector because other trends of mathematical science were intensively developing in new mathematical subdivisions - Computational Math Sector (CMS) and Mathematical Logic and Programming Sector (MLPS).
Spring of 1965

seni rumai625x400

The building of IPhM was accomplished on the K. Požėlos 54 st. (now Goštauto 12 st.) in Vilnius.
1 October 1965 telksnys j300x436

The Recognition Processes sector (RPS) was established. Head Dr. Laimutis Telksnys.
At that time, there emerged a pressing necessity for Lithuanian Science not to stand aloof from the rapidly developing control problems science in the world and to begin systematic research of cybernetic problems.
The germs of these researches that had formed at the institute in connection with computer technique reliability problems have already become insufficient. Therefore a leading designer of the Vilnius Computing machine plant Laimutis Telksnys was invited to the Institute. A group of employees came here together with him. They made a basis for a new sector. Since that time, along with the trends of mathematical and physical sciences, the scientific research of a third trend-cybernetics-has began rapidly developing.
1966 The Institute of Physics and Mathematics (IPhM) was granted the first category.
This meant a kind of recognition of the work pursued at the Institute which offered better opportunities for further development.
23 November 1966

The Presidium of the Lithuanian Academy of Sciences adopts a resolution on the reorganization of the Institute of Physics and Mathematics (IPhM).
This is the first reorganization of IPhM.

Among the research on the physical profile of IPhM, the trend of experimental semiconductor physics stood out vividly, in which, thanks to the talent and organizational efforts of the then director Juras Požėla, an original school shoots up with ponderable scientific achievements and highly qualified scientific staff. That is why the new institute - SPhI - has been originated based on semiconductor physics subdivisions.

1967-1976 Institute of Physics and Mathematics before the second reorganization

1 January 1967

stat dir300x436Vytautas Statulevičius becomes the director of the Institute of Physics and Mathematics (IPhM). Dr. Laimutis Telksnys, Dr. Mifodijus Sapagovas, and Prof. Boleslovas Styro are deputy directors.
After separating the Semiconductor Physics Institute (SPhI) from the IPhM, the latter included the subdivisions only of mathematical and cybernetics profile, Computing Center, the subdivisions of theoretical physics, and Department of Nuclear Physics and Radioactive isotopes. 
During the reorganization of the Institute, changes were made to the structure of the Institute:

  • Vytautas Liesis was appointed the chief of The Electronic Computing Machine Laboratory (ECML)
  • The Mathematical Logic and Programming sector (MLPS) was renamed the Mathematical Logic and Algorithm Theory sector (MLATS). Vilius Matulis remained its head. After transferring the programming and problem-solving work to the MLATS, the new title better reflected the research work trend, pursued in the sector.

New sectors were established:

  • The Numerical Analysis Sector (NAS). Dr. Mifodijus Sapagovas was nominated as its head.
  • The Operations Research Sector (ORS). Dr. Eduardas Vilkas was nominated as its head. 
  • The Programming and Problem Solving Sector (PPSS). Dr. Bronius Kvedaras became its head.
  • The Laboratory of Perforated Computing Machines (LPCM). Jonas Algis Petkevičius was appointed head of the laboratory.

28 March 1968

besm 4 627x400The BESM-4 computer was put into action. Engineer Antanas Čeida was appointed the head of the machine maintenance crew.

This computer was much more reliable and powerful than BESM-2M: its memory was 4000 words with 45 bits each, Magnetic Discs (MD) with 64000 words, and 4 Magnetic Tapes (MT). Its speed was 2000 commands per second. Programming was performed by machine codes; later the programming language ALGOL-60 was implemented.
5 May 1969

Boleslovas Binkauskas was appointed the head of The Electronic Computing Machine Laboratory (ECML). Vytautas Liesis becomes the chief of the computer BESM-2M maintenance crew.

16 November 1969

The Optimal Solution Theory Sector (OSTS) was set up. Its head was Prof. Dr. Jonas Mockus.
To establish more favorable conditions for a new trend of scientific research - optimization methods of multiextremal functions - Presidium of the Lithuanian Academy of Sciences has decided to move a part of the Extremal Problem Laboratory researchers (headed by Jonas Mockus) of the Institute of Physical-Technical Power Problems in Kaunas to the Institute of Physics and Mathematics. They comprised the Optimal Solution Theory Sector.
The Software Sector (SS) was established. Dr. Pranas Rumšas was nominated as its head. 
A group of specialists has successfully worked at the PPSS for a long time. They took care of the software assimilation, handling, and maintenance for "EC" - series computers. Namely, these people comprised the basis of the new sector and they were entrusted with the creation, adaptation, and exploitation of computer software.
The Algorithms and Software Foundation (ASF) was founded in MSS (head Vilma Dragūnienė).

The Mathematical Statistics Sector (MSS) was established. Prof. Bronius Grigelionis was its head.
After the qualified staff have considerably grown in number and the scientific research topics expanded, the MSS was set up based on the Probability Theory Sector. 
Spring of 1971 BESM-2M was disconnected. Thousands of physicists, mathematicians, astronomers, engineers, medics, and economists of the republic used the computer BESM-2M, however, its exploitation was getting detrimental in comparison to others, the new computers of that time. Therefore it was written off and demounted, and a new electronic computer BESM-6 was mounted in its place. 
18 October 1971

Gediminas Baguška started to work as deputy director for economic affairs.

 
June 1972
The first  BESM-6 computer was put into action. Engineer Petras Šulcas was appointed the chief of the computer maintenance crew.
To satisfy the rapidly growing needs of users, the best way was to expand the computer center, to introduce new more powerful computing machines. BESM-6 had more memory, replaceable magnetic disks, 8 magnetic tape devices, and executed about 1 million operations per second. It possessed much more convenient and powerful software and worked in the common usage mode. 
16 January 1974 An independent Fund for Algorithms and Programs (FAP) was established, reporting to the Deputy Director, head of the Calculation Center. The group was headed by V. Dragūnienė.
July 1976

The second ESM BESM-6 is launched.
Like the first one, it was serviced by a team led by P. Šulcas.
The two computing machines were interconnected and shared resources. This greatly increased the efficiency of problem-solving.
In 1992 both computers BESM-6 were disconnected.
4 October 1976

masiulis250x364

Established The Information and Patent Sector (IPS). Head of Sector – Dr. Jonas Masiulis.
The establishment of the Unit was motivated by the need to better provide scientific information to the Institute's staff and by the rapid development of the invention. At that time, up to 50 applications for inventions were submitted annually by the staff of the Institute, and about two-thirds of these applications were accepted and granted a copyright.
1 January 1977

The second reorganization of the IPhM
The rapid expansion of the IPhM research directions and problems, the growth of its technical material base in computing, cybernetics, astronomy, and experimental physics, and a large number of highly qualified, but quite differently profiled, researchers made the Institute too universal, a kind of small academy. At the end of 1976, the Institute had more than 600 employees, including 10 PhDs, more than 120 PhD candidates, and 47 postgraduate students.

However, neither too narrow a specialization nor too broad a universality is conducive to effective research. This has led to the reorganization of the IPhM.

1977-1990 Institute of Mathematics and Cybernetics

1 January 1977

The Institute of Physics and Mathematics splits into two institutes:
• Institute of Mathematics and Cybernetics (IMC). Prof. Dr. V. Statulevičius is appointed director of the Institute. The deputy directors are Prof. Laimutis Telksnys (Science), Prof. Mifodijus Sapagovas (Computing Centre), and Gediminas Baguška (Economic Affairs).

• Institute of Physics. J. Viščakas is appointed director of the Institute.
During the reorganization,n the number of laboratories and sectors of mathematical and cybernetic trends in IMC has not changed. However, a more rapid reformation of the Institute, about the new tasks, posed on it, to render more particular support to the Republican economy, required a respective reorganization of subdivisions. Two major scientific research trends were confirmed for the Institute of Mathematics and Cybernetics during the reorganization which concurrently was the profiling trends at the Lithuanian SSR Academy of Sciences. These were:
1) Probability theory and its application in solving control problems;
2) Computerization of scientific research
These trends encompassed all the scientific topics that in the former Institute of Physics and Mathematics were attributed to the profile of mathematics and cybernetics.
27 January 1977 The Programming and Problem Solving Sector (PPSS) was renamed into the Differential Equations Sector (DES) headed by Dr. Bronius Kvedaras.
