Dion has dabbled in math for a while. In elementary and high school, he was the national winner of the Metrobank Math Challenge. This year, he will compete in the International Mathematical Olympiad. Lately, he discovered informatics and found the shift to algorithms instinctive. In college, he plans to pursue computer science to develop smart cities.

Steven

Steven Reyes
grade 10, Saint Jude Catholic School

Steven first discovered programming around 5 years ago when he created circuits and logic gates in Minecraft. Creating these contraptions are like solving computational problems, both of which he enjoys indulging in. The joy he finds in problem-solving extends to the different math, science, and programming competitions he participates in, and even to teaching fellow schoolmates how to approach various kinds of puzzles.

Miko

Ron Mikhael Surara
grade 11, Philippine Science High School – Bicol Region Campus

Miko initially joined NOI for the freebies but continued to pursue it as he grew to love solving algorithmic problems. He has been joining the NOI for four years, always shortlisted for the IOI team in every attempt. Formerly, he was President of the Advanced Programming Club (APC) in his school. Although not a member of this club anymore, he still teaches younger aspiring students. When he’s not solving algorithmic problems, he plays games such as LoL and Osu with his friends and reads manga and books. He also likes to watch anime, series, and movies. He also has interests in drawing and calligraphy, as well as in sports, especially table tennis and lawn tennis. He plans to take computer science in college and use his programming skills to help improve other fields in science and technology.

The NOI.PH 2019 National Finals was held in Ateneo De Manila University’s Faura Hall last 6 – 7 April 2019. The 28 official finalists competed over two five-hour rounds, each of which consisted of five problems.

Invited to participate in the finals were the top 30 at the NOI.PH 2019 National Eliminations, a 222-hour online competition held last 18 – 27 January 2019, where 141 students from all over the country solved fourteen problems of varying difficulty.

Students who almost made it to the top 30 also made it as observers. Philippine Science High School Bicol Region Campus (PSHS 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.

This year’s observers were Adalbert Apuya, Lance Benedict Cabrera, Jose Enrique Ramirez and Ralph Richard Yanto. All are incoming Grade 10 students of PSHS BRC, and they have set themselves up for success in the next few years by gaining experience on what the national finals feels like.

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.

Events

The first day of the contest started with the opening ceremonies. NOI.PH President Vernon Gutierrez began with a speech, and said “We’re here because we love solving problems. Let’s all have some fun this weekend!”

He also discussed the rules to the competition and some notes on using the compiler before the Practice Round of the competition. In the Practice Round, students spent 90 minutes familiarizing themselves with the computers through solving some problems.

After lunch, the first round of the finals began. A mirror of the problems began shortly after. During Round 1, the NOI.PH Organizing Team held a short meeting with the coaches to discuss the state of competitive programming in their respective high schools.

Round 2 began in the morning of the second day, with a mirror contest being held again. Lunch was served after the end of the round, and NOI.PH Head Judge Kevin Atienza discussed the solutions to the problems after lunch.

Finally, the awarding was held, and the top three students won the surprise prize of a free shirt, containing source code overlaid on an NOI logo.

NOI.PH Finals Round 1

Header for the problem Tower Bloxx

Round 1’s friendly rivalry began with Magkaribal sa Arnibal. Vincent Dela Cruz made the first submission within twelve minutes, getting 40 points. The first full solution was from Steven Chua two minutes later. By the end of the contest, twenty-five of the finalists solved the problem completely.

The Room was not a problem that teared contestants apart. In fact, of the twenty-one contestants who attempted the problem, ten solved the first subtask to get 30 points. Steven Reyes and Dion Ong solved the second substask as well to get 69 points, while Ron Surara and Dan Baterisna managed to solve the problem completely. Good thinking!

Sixteen competitors submitted code for Baby Come Bak, with five of them getting nonzero scores. Vash Ancheta and Clyde Borrega solved the second subtask to get 6 points, while Ron solved the third subtask to get 22 points. After several submissions scoring less points, Dan and Steven C. came back to Baby Come Bak to solve both the second and third subtasks to get 28 points.

Tower Bloxx was not only a popular game, but a popular problem for contestants to try with twenty-three submissions. It’s the first partial scoring task to appear in the NOI.PH Finals. Twenty submissions managed to get a nonzero score. Eight of these scored at least 20 points, with AC Mabute scoring the highest at 48.94 points. AC not only topped the towers, but he also topped the problem.

Two contestants submitted submitted code for Sumbong Centers, but unfortunately, no one managed to solve for the number of solb sets and get a nonzero score.

NOI.PH Finals Round 2

When it comes to programming, contestants are logging prepared! Illegal Logging saw quick full solves from Ryan Shao, Raphael Dalida, and Rae Samonte within the first seven minutes. Twenty-six of the finalists got a nonzero score, with twenty-three of them solving the problem fully.

Among the twenty-one participants who played the role of Mr. Kupido, sixteen got a nonzero score. Of these, eight got 6 points and four got 12 points. Frederick Tan and Ryan got 21 points, while Vincent and Steven C. were the best matchmakers, both getting 27 points.

Fifteen participants submitted code to BATIBots. Rae, Steven C., and Vincent Dela Cruz solved the first subtask to get 17 points, while Dion, Ryan, Ron, and Steven R. solved the first two subtasks to get 32 points. Dan demonstrated his Brainy Augmented Transcendental Intelligence by solving enough subtasks to get 62 points.

Sorting the Planets saw fifteen students submitting code. Only three participants got nonzero scores: Dion solved the first two subtasks to get 29 points, while Ron and Dan solved the first three subtasks to get 40 points. Hopefully these students will continue to follow Kevin’s example.

Finally, only four students attempted to draw their own Cartogram to a better place. Vincent did not take a fall on the road, and followed the cartogram that lead to a nonzero score of 19 points.

Six Filipino students bagged medals in Singapore’s 22nd National Olympiad in Informatics held last March 23, 2019 at the National University of Singapore.

Dan Alden Baterisna won a gold medal, making this his second year in a row of winning gold after last year’s performance. Ron Mikhael Surara, Dion Stephan Ong, and Steven Chua won silver, while Clyde Lawrence Borrega and Raphael Dylan Dalida won bronze.

Dan’s win is the country’s third gold medal from the Singapore tilt; with Robin Christopher Yu being the country’s first gold medalist. The haul marks Ron’s and Dion’s second silver medals. Among the delegation, Steven, Clyde, and Raphael ranked well despite being first-timers to the competition.

Students from Singapore joined with participants from other foreign countries, including the Philippines, Indonesia, Malaysia, Thailand, and Vietnam. The Philippines has been joining the Singapore National Olympiad (NOI.SG) ever since they opened the contest to foreign participants back in 2016.

The six students were chosen based on their scores in the Singapore NOI Preliminary Round, where they ranked the best among all Filipino participants. The students were accompanied by NOI.PH trainers Vernon Gutierrez and Robin Yu, along with several other coaches and parents.

The contest consisted of a five-hour session consisting of five problems, held in the I³ Building of the campus. Each contestant must write a program that outputs an answer to the problem given a set of inputs, following the constraints given in the problem’s statement.

A practice round was held the previous day, on March 22, 2019. Other events were also held, such as Capture the Flag, a computer security competition where participants apply their programming skills to challenges in web, networking, reverse engineering, cryptography, and related fields. Dan placed within the top ten in this event and won a power bank.

We are happy to announce the Philippine team to this year’s International Olympiad in Informatics. They will represent the country in the most prestigious informatics olympiad. The contest consists of two five-hour sessions of solving algorithmic problems and coding up solutions.

 

Dan

Dan Baterisna
grade 10, Colegio San Agustin Makati

Dan Baterisna is one who enjoys the social aspects of academic contests. He participates in a lot of team contests, providing his science and technology expertise in general knowledge competitions. When he’s not busy pwning algorithmic challenges, you will most likely see him pwning his friends in online games such as Rules of Survival. In the future, he plans to take up computer science with the goal of eventually working with local tech startups.

 

Franz

Franz Cesista
grade 12, Philippine Science High School – Eastern Visayas Campus
coach: Cary Von Alano

Franz Cesista is not content with just learning, he also enjoys sharing it to his interested peers. He shares what he learns in the countless contests and seminars by lecturing, for example, in his school’s programming club. His pursuit of knowledge manifests as well when he unwinds as he often plays complex simulation games such as Factorio. For college, he plans to study mathematics and eventually focus on artificial intelligence.

 

CJ

CJ Quines
grade 12, Valenzuela City School of Mathematics and Science
coach: Ruel Dogma

CJ Quines is the artsy type of scientist. His hobbies include calligraphy, ukelele, and the art of proving mathematical theorems. In fact he recently placed second in a science fair sponsored by Intel. There, he tackled a special case of an NP-complete problem related to planar graphs. He also maintains a blog where he writes about his experiences in various competitions and conferences. After college, he plans on becoming a data scientist.

 

Andrew

Andrew Ting
grade 12, Xavier School San Juan

Andrew Ting has been drumming in his school’s pep rallies since grade school. He found his interest in programming through the game LittleBigPlanet. When he’s not beating the drums, he is likely drumming up interest in algorithms as an officer of his school’s programming club. As a student who’s into game dev, Andrew plans to transition from playing rhythm games to developing them by taking up computer science in college.

 

The team will be accompanied by Team Leaders Kevin Atienza and Vernon Gutierrez.
