Selection Rules
Introduction
-
Teams qualify for regional contest from subregional contests.
-
This document describes selection rules for teams competing at
St. Petersburg site.
Quotas Assignment Rules
-
Each subregion has a particular number of teams Q
that can proceed to regional contest. This number is
determined using three main parameters:
- Basic: each subregion can send at least two teams
to the regional contest
- Geographic: subregions involving teams from many different
areas and cities get additional teams allowed to proceed
to regional contest.
- Rewards: based on the results of the previous regional contest,
subregions get additional teams allowed to proceed to regional
contest.
- Teams: for each 50 participating teams completely registered
at icpc.baylor.edu
before the subregional contest the subregion has
one additional team.
Therefore Q = 2 + G + R + T where
G is the geographic parameter,
R is the rewards parameter, and
T is the teams parameter.
-
For the purpose of determining quotas for different subregions
two special sets of teams are defined, called the T-sets.
- Consider all teams that participated in St Petersburg
site in previous regional contest, ordered by their result
on the contest. Remove all teams except
the two best teams from each university (therefore,
remove third and fourth worst teams of the universities
that had more than two teams on the contest). Fifteen
best teams in the list are called the T15 teams.
- Consider all teams that participated in St Petersburg
site in previous regional contest, ordered by their result
on the contest. Remove all teams except
the three best teams from each university (therefore,
remove the fourth worst team of the universities
that had more than three teams on the contest). Fifty
best teams in the list are called the T50 teams.
-
For each subregion rewards parameter R is equal to
the number of teams from it in T50 teams.
-
Each university can have two teams qualified to the
regional contest.
-
Universities that have at least two teams
in T15 teams are allowed to have three teams qualified
to the regional contest.
-
Universities can be allowed additional teams for hosting subregional
contest, hosting global training camps, etc.
Proceeding to the Regional Contest
-
Teams proceeding to the regional contest are determined using the
following rules.
-
Teams taking part in a subregional contest are ordered by their
result in the contest.
-
All teams are removed from the list, except the top K
teams from each university, where K is the number
of teams allowed to qualify to the regional contest for the university
(K is 2 or 3, depeinding on the university).
-
Top Q teams in the resulting list qualify for the
regional contest, where Q is the number of teams that
are allowed to proceed to the regional contest for this subregion.
