Lithuanian Olympiads in Informatics
Lithuanian National Olympiad in Informatics is a competition for
secondary school students in Lithuania, organized by
Lithuanian Ministery of
Institute of Mathematics and Informatics together with
publishing company TEV.
Although Lithuanian Olympiads in Informatics were started in 1990,
a student from Lithuania participated in the first IOI in 1989 in Bulgaria
as a member of Soviet Union team. It was Andrius Čepaitis.
He won the gold medal in this IOI. Lithuania as a
country joined the IOI community only in 1992.
Students in the National Olympiad are divided into five groups
according to the grades. Nevertheless there are only two
sets of tasks. The first set is for junior students (9th grade and
below, which is 14 years and below). The second set is for senior students
(10th–12th grades, 15–17 years).
Each Olympiad consists of three rounds. The School round
(first round) with over 3000 students comes in November. The
National Evaluation Comity (NEC) proposes tasks for this round. However
there is much freedom in this round as well as in the second round.
Each school has the right to choose their own tasks, programming languages,
compilers, evaluation criteria. All the evaluation is done at schools.
In the Regional round (second round), which is held in December,
participate around one thousand students. Each region can use either
the tasks proposed by the NEC or choose their own as in the school round.
All the evaluation is done at regions. After the Regional competition the
region submits the names of contestants that will go further to the National
Over 250 students participate in the National round which
is divided into two parts. It would be too complicated to find over
250 computers in one place . The first part takes place on-line and
it is conducted in one day in all the regions at the same time. Contestants
have five hours to solve two problems of algorithmic nature and right after
the competition all the solutions are sent to the NEC via e-mail. The solutions
are submitted to and evaluated by the automatic submitting and grading
system. The NEC chooses the best 45 students from all five groups and invites
them to the second part of the National round.

The second part of the National round lasts about four days with
two contest days. Contestants have to solve five problems during two
days. The members of the NEC evaluate the programs with automatic evaluation
program. In some tasks contestants are asked to write not only the programs
but also the descriptions of ideas which are also evaluated. The
readability and structure of the programs is also evaluated in
case the program gained over 50 percent of points for the tests.

All the problems in the Olympiad are of algorithmic nature,
similar to IOI problems. Some of them, especially in the first round
