The NOI.PH 2020 National Finals were held virtually last 8 – 9 August 2020. The 31 official finalists competed over two five-hour rounds, each of which consisted of five problems.
Invited to participate in the finals were the top 31 at the NOI.PH 2020 National Eliminations, a 222-hour online competition held last 17 – 26 January 2020, where 148 students from all over the country solved seventeen problems of varying difficulty.
Other students were invited as non-finalist participants. Schools like Philippine Science High School (PSHS) Bicol Region Campus (BRC), coached by Mr. John Rainer Joaquin, had more than six students who scored high enough in the national eliminations. Thus, the top six students from the school attended as official participants.
From PSHS BRC we have Johnbell De Leon, Jose Enrique Ramirez, and Ralph Richard Yanto. NOI.PH also invited other non-finalist participants like Edric Ato from Manila Science HS, and Ezra Magbanua from PSHS Central Visayas Campus. All students were in Grades 10 or 11, and will have another year to join the competition.
In the NOI.PH, finalists tested their endurance by solving five challenging programming tasks during each day’s five-hour session. Contestants used their programming and analytical skills to create data structures and algorithms to solve each task using a program.
A mirror of the Round 1 and Round 2 problems are on Codeforces.
One week before the contest, on 31 July, there was an advance practice round. The two-hour round helped contestants and organizers ensure that the contest system was functional for the finals.
The first day of the contest started with an opening ceremony livestream. After the national anthem, the Department of Science and Technology – Science Education Institute’s Director, Dr. Josette Biyo, gave some opening remarks. “This is truly a great platform to train students to become problem solvers,” Dr. Biyo said of NOI.PH.
After the inspiring message, NOI.PH President Marte Soliza delivered his own remarks. Then, Contest Co-Director Vernon Gutierrez discussed the rules to the competition before the Practice Round of the competition. In the Practice Round, students spent 90 minutes familiarizing themselves with the contest system through solving some problems.
After a one-hour break, the first round of the finals began, and after the first round, there were some reminders for the second day of the program.
Round 2 began in the morning of the second day. After the competition, NOI.PH Head Judge Kevin Atienza went over some of the main ideas of the problems after lunch in a livestream. He encouraged competitors to attempt the problems again in the mirror that happened the next week.
Finally, the awarding livestream happened. Certificates were presented, and various special awards were awarded. The top six contestants were also asked to give short messages about their training.
Contestants Dan Alden Baterisna, Steven Reyes, and Steven Chua were the first to get 101, 201, and 301 points in the first day and got the prize of a Steam game; similarly, contestants Dion Stephan Ong, and Reyes were the first to get 101 and 201 points in the second day.
Six Steam games were also raffled to contestants, with the number of entries proportional to their score. Contestants Lance Benedict Cabrera, Reyes, Baterisna, Ron Mikhael Surara, and Jose Enrique Ramirez, won the raffle.
Last in the special awards were for the Rookie of the Year awards, given to the highest-scoring first-time finalists. Runner-ups Kain Colin Chua and Harvey Shawn Chua won a mouse, and Enrico Rolando Martinez won a keyboard.
Finally, the top ten were awarded. Honorable mentions were Marc Joshua Ayalde, Harvey Shawn Chua, Enrico Rolando Martinez, and Surara, ranked tenth through seventh, and each won PhP 1,500. Ranks sixth through fourth, Raphael Dylan Dalida, Frederick Ivan Tan, and Dion Stephan Ong, were bronze medalists, each winning PhP 2,000.
The third and second places, Reyes and Steven Chua, each won a silver medal PhP 3,000. Baterisna, the top ranked contestant, won a gold medal and PhP 6,000. Steven Chua and Baterisna also won two of the four spots on the Philippine team to the IOI.
