CAMA (Amateur Competition in Mathematics and Algorithms) is a competition created with the aim of promoting
academic
Olympiads in Spain. Founded and maintained by high school students from different regions of Spain, it aims to
attract
students interested in informatics and mathematics to experience what these discipline Olympiads are like.
Training
is also provided to help them learn and enhance their knowledge. However, the contest is open to anyone who wishes
to
participate, whether Spanish or foreign, and whether they are in high school or not. However, there will be prizes
reserved for Spanish high school students.
There are two categories: mathematics and informatics.
The competition will take place over two days. The mathematics round will be on November 23rd, while the informatics round will be on November 24th.
The mathematics round will follow a format similar to the IMO (International Mathematical Olympiad), while the
computer
science round will adapt to the ICPC (International Collegiate Programming Contest) format. The contest will
consist of
two divisions, advanced and basic. The basic division is intended for those participants who are beginners in the
respective discipline and have limited knowledge, while the advanced division is geared toward those with
experience in
Olympiads. The number of problems and the scoring system will be the same (or very similar) in both divisions.
Information about the problems
For the informatics round, each division will have approximately 8 problems. In the mathematics round, each
division will have 5 IMO-style problems.
Rules
Internet can be used during the contest, but communication with other participants while the contest is in
progress is
prohibited. The contest is an individual competition. We will review the solutions of the winners, and if we
suspect
anyone has cheated, they will be disqualified. Additionally, we request that participants refrain from using
artificial
intelligence to solve problems in the basic division, as some of them are designed to be solvable by anyone.
Scoring
For the mathematics round, each IMO-style problem is worth 7 points, and partial scores can be received based on
the
progress made. This means that if a participant does not reach the solution but gets closer, they can receive 5 or
6
points, for example. Additionally, for the basic division, each correct answer in the multiple-choice test format
will
add 1 point to the total score, while any incorrect answer will deduct 0.25 points. No points will be deducted for
unanswered questions.
For the informatics round, each problem adds 1 point to the participant's score when solved. A problem will
only
count as correct if the participant's solution correctly solves all private test cases for the problem.
Participants are
ranked by score. In the event of a tie in points, the time spent on solving problems will be used as a tiebreaker,
so
participants with less time spent will appear higher in the ranking for equal scores. The calculation of time
spent is
done as follows:
For each accepted problem, the time elapsed between the start of the contest and the moment of the correct
submission is checked, and that time is added to the participant's total time spent.
Each incorrect submission of a problem that is ultimately accepted results in a penalty of 20 minutes
(compilation
errors do not count).
After the first correct submission of a problem, any subsequent submissions for the same problem are not
counted
for penalty purposes.
