NUS Team @ ACM ICPC World Finals 2017

NUS team TeamTam: Muhammad Rais Fathin Mudzakir (3rd year student), Agus Sentosa Hermawan (1st year student), and How Si Wei (2nd year student) has competed in the annual ACM ICPC World Finals 2017 in Rapid City, USA on 20-25 May 2016.

TeamTam obtained raw rank 32/133 teams but officially classified as rank joint-20. This is on par with NUS recent results since 2014 (joint-19/122/2014, joint-28/125/2015, joint-14/128/2016). Congratulations.

NUS ICPC Activities in 2017 and 2018 are donated by these generous companies:


ACM ICPC Selection Contest For Regionals 2017

Date and Time: Saturday, 02 September 2017, 1PM-6PM SGT (end of Week 03, lunch and dinner provided).
Come to COM1-B(asement) by 12.15PM for lunch and stay back after 6PM for team formation, also with dinner.
Venue: COM1-B-PL2 (capacity 46).
Format: Individual selection contest to determine individual coder rankings, using ICPC rules (e.g. 25 pages hardcopy reference material), but individual instead of team of three.
Problems are set by Dr Steven Halim with help from one senior two times ex NUS ACM ICPC world finalists: Nguyen Tan Sy Nguyen.

As we also do not host ACM ICPC Asia Singapore in 2017, we have gone/will go to various Asian PP sites this year, see below.

This selection contest has been concluded.
The list of 18 selected contestants for this AY 2017/2018 can be found here.
The newly selected NUS ACM ICPC team members are given one-year 24/7 access to NUS ACM ICPC Lab (COM2-02-15).

NUS ACM ICPC Plans for Regionals 2017

Using donations from three companies mentioned above, we will send up to 6 NUS teams (that is, up to 18 students) to 4 Asian PP sites in 2017.

Basically, the rationale for choosing these sites are:

  1. Does (any of) NUS team has theoretical chance to win it?
  2. If the first objective is realistically too hard, then we ask: Can (any of) NUS team be in top 3 in that site (for ACM ICPC World Finals 2018 qualification)?
  3. Do the contest dates clash with NUS S1 final assessment (exam) dates (25 Nov-09 Dec 2017)? (too many administrative problems otherwise)
  4. Can we actually afford it or is it economical? (remember that we will send lots of teams to multiple sites this year)

Based on this 2017 Asia Pacific & Indochina Peninsula (PP) data, we have competed in:

  1. The ACM ICPC Asia Jakarta (Indonesia) 2017 (List of teams or the one with contestant names).
    Actual: 10-11-12-13 Nov 2017 (end of NUS Week 12, start of NUS Week 13).
    NUS teams: ALL SIX NUS teams 2017: Pandamiao, BubbleTeaM, DomiNUS, 3Freshmen, 3body, Pikachu.
    NUS staff-in-charge: Dr Steven Halim (Senior Lecturer).
    RESULTS: DomiNUS (Champion), 3body (5th place), Pandamiao (6th place), BubbleTeaM (7th place), 3Freshmen (9th place), Pikachu (15th place), final scoreboard.
    As usual, this site is also the benchmark site regarding which NUS team goes to WF18 — in the possible scenario when we have other NUS team(s) qualifying to WF18.
    As DomiNUS already get WF18 slot from this site and also the highest ranked NUS team in Jakarta site, DomiNUS will be sent to ACM ICPC World Finals 2018 in Beijing, 15-20 April 2018, regardless of the result of 4 other future sites below.

NUS teams will also go to:

  1. The ACM ICPC Asia Ho Chi Minh City, (Vietnam) 2017 (List of teams).
    Actual: 6-7-8-9 December 2017 (on NUS exam week 02 and all DomiNUS members have completed their final exams by then).
    This is the first time (in many years) that NUS send an official team to a Vietnam site (last year Tourism competed largely on their own).
    NUS team: DomiNUS (free return ticket to HCMC, VNM for their December 2017 holiday and their choice return flight to Singapore in January 2018).
    NUS staff-in-charge: Dr Zhao Jin (Lecturer).
    RESULTS: TBA on ~9 Dec 2017.
  2. The ACM ICPC Asia Yangon (Myanmar), 2017 (List of teams).
    Actual: 8-9-10-11 December 2017 (yes, no longer clash with NUS exams).
    We got one WF17 qualification slot from here last year (team A0, but was not used)
    NUS team: 3Freshmen.
    NUS staff-in-charge: Prof Tan Sun Teck.
    RESULTS: TBA on ~11 Dec 2017.
  3. The ACM ICPC Asia Manila, (Philippines), 2017 (List of teams).
    Actual: 12-13-14-15 December 2017, does not clash with NUS exams and thus we have enough time to practice.
    We got medium result in 2016 here.
    NUS team: Pandamiao.
    NUS staff-in-charge: Dr Steven Halim (Senior Lecturer).
    RESULTS: TBA on ~15 Dec 2017.
  4. The ACM ICPC Asia Nakhon Pathom, (Thailand) 2017 (List of teams).
    Actual: 20-21-22-23 December 2017 (they changed date :O, so now no major timing clash but BubbleTeaM has to stay back throughout the early part of NUS holiday period).
    NUS team: BubbleTeaM
    NUS staff-in-charge: Associate Professor Tan Sun Teck.
    The host (Mahidol University) is at Nakhon Pathom, which is close to Bangkok.
    We usually get reasonably good results here but historically it is hard to win here.
    RESULTS: TBA on ~23 Dec 2017.

Cannot go due to various reasons:

  1. The ACM ICPC Asia Daejeon (South Korea), Contest date on 11 Nov 2017, final ranking (WF18: SNU (Medal team), KAIST (Medal team), Korea U (TBC)).
  2. The ACM ICPC Asia Hua Lien, (Taiwan), Contest date on 25 Nov 2017.
  3. The ACM ICPC Asia Tsukuba (Japan), Contest date on 17 Dec 2017 (those going to Tsukuba may also go to Manila but unlikely as they are back to back).
