During 1987-2010 the research was carried out in the field of building intellectualized computer systems and expert systems. Research and study in the area of statistical expert system creation were carried out jointly with the laboratory for probability theory and computer statistics.

Before 1986 the laboratory paid principal attention to the problems of system software maintenance for different computer generations.

### Main activity results

The researchers of the Laboratory for Information Computer Technologies made some contribution to the following science fields:**Optimal routing networking games**

We find the lower bound for Price of Anarchy (PoA) for the general case of N machines in the maximizing the minimum machine delay game with uniformly related machines. For the case of 3 machines we find its exact value. We prove that the PoA does not change or increases when an additional third machine is included into the system with two machines. Also we propose a method of computation the PoA value and illustrate it for 3 machines [1].
