Competition Venue Assignment
The main purpose of using two competition venues is to facilitate social distancing to reduce the risk of disease transmission. Contestants’ preference, capacity utilization and travel time will be taken into account when allocating competition venue.
Note: The organizing committee reserves the right to override any venue assignment.
The capacities of the two competition venues are as follows: (Subject to change if machines are found inoperative or for other reasons)
Yan Oi Tong Tin Ka Ping Secondary School: C1 = 40 (2 computer rooms)
Pui Ching Middle School: C2 = 48 (3 computer rooms)
Assume that at the end of the registration period, N contestants in a particular group registered for the Final Event, then the target utilization shall be U = N / (C1 + C2). The target number of contestants Tv for a competition venue v would be its capacity Cv multiplied by U. Denote Pv be the number of contestants who prefer the competition venue v. If Pv > T then T would be rounded up. Otherwise T would be rounded down.
For those contestants who prefer the venue which has Pv ≤ Tv, they will all be assigned to the venue v.
For those contestants who prefer the other venue, they will be assigned to either venue based on their travel time score delta.
Travel Time Score
We use the address of their school to approximate a contestant’s location. The transit duration from the contestant’s school to the two competition venues (Arrive by 08:30 on 18th July, 2020) is obtained using Google Maps API. If the transit duration is Dv seconds, then the travel time score Sv = e(Dv/3600). The travel time score delta is the score for Yan Oi Tong Tin Ka Ping Secondary School minus the score for Pui Ching Middle School.
For example, in case Pv ≤ Tv for Yan Oi Tong Tin Ka Ping Secondary School, then among the contestants who prefer Pui Ching Middle School, the (Tv–Pv) contestants with the least score deltas will be assigned to Yan Oi Tong Tin Ka Ping Secondary School. Tie-breaker for contestants having the same delta (same school): The contestants who rank higher in the nomination form will get their preferred venue.
