Asia Pacific Rules for WF teams Selection for 2019

                          (Draft 09/27/2019)

A.    WF slots

1.      WF slots allocated to Asia Pacific will be directly decided from ICPC Headquarter.

2.      South Pacific Independent Regional Contest is 100% independent and separated from other regional sites in Asia Pacific in terms organization, WF team selections, and other Asia Pacific operations.

3.       (?) The Institute of a WF medal team from most recent WF, will not automatically have a team advanced to next WF.

4.      The contest site participation score will be calculated based on Asia Council Rules among those Regional Contests within Asia Pacific. The WF teams selection will be decided by the formula in item (B).

5.      There will be no Asia Pacific Final in 2019. The revised rules in 2020 will be announced later.  

B.     Promoting teams to WF using the contest site participation score - Shieh-Ishihata formula.

Each site has its own site participation score (call it S).  Collect all instances of teams from all sites.  They have the WF-slot Advancing rank at a site, (call this rank R).  Divide the rank minus 1 by the site score, and assign this value ((R - 1) / S) to the team instance.  Sort the instances in ascending order using the value assigned to them.  Strike out the second or later instances from a same university in the sorted list.  Finally, qualify the exact number of universities from the head of the sorted list.

Before applying Shieh-Ishihata formula, the contest site participation score of a Asia Pacific site will be increased by 0.02 * n points  if the site has n foreign teams and a max of n=25. This will encourage the hosting of more foreign teams.

The following is the rationale of the rule.

The site participation score of a site is, in principle, the number of teams to be chosen from the site.  Stating differently, the number of teams chosen from a site should be proportional to the site score.

Dividing the rank by the site score and sorting team instances using this value exactly reflects this principle.

Subtracting one from the rank corresponds to the fact that the champion university at a site should always be qualified, that is, be treated somewhat differently from other lower rank teams.

Note that, according to the rule, a champion university at a site is always qualified.  If the rank is 1, R - 1 is zero, so the team instance is always at the head of the sorted list.

Part of Asia Rules Applied only to Asia Pacific Region:

 Preference Team for Under-represented Countries in Asia Pacific:

             If the WF participation slot is available, and if there are too many countries in Asia Pacific 

             have no representation to WF, Asia Pacific Steering Committee or Asia Council Director may

             reserve a participation slot for one of these countries. The team receiving the under-represented

             preference must be ranked 10 or better in a university ranking in any Asia site. This preference is

             limited to a max of one team per year. The same country can accept this under-representation
             preference at most once every three years.
