19th PMO: Instructions for Qualifying Stage (Region 5)

pmo

The 19th Philippine Mathematical Olympiad Qualifying Stage for Region V will be held this October 22, 2016, Saturday, at the Ateneo de Naga University, Naga City, Camarines Sur.  The exam rooms are at the second and third floors of the Francis C. Dolan, S.J. Hall; registration will be done in the same building.

If you sent your application forms through e-mail, please bring the original application forms with you and submit them to the registration staff on October 22, 2016, if possible.

Participants and coaches must bring identification cards that have ID pictures, preferably those issued by their schools.

Registration starts at 10:00 am.  Participants should be in their assigned rooms by 1:45 pm.  The exam will start at 2:00 pm and is expected to last 2 hours.  Participants who arrive late must take the exam in a room reserved for late-comers (and not their assigned room) so as not to disturb the other participants who started on time.  The exam ends at 4:00 pm, even for those who arrived late.

Once the exam has started, participants may not leave the room until it has ended.  Participants who need to use the bathroom must do so before the exam starts.

Participants who leave the room before the exam has ended are considered to have finished the exam; they must submit their questionnaires and answer sheets to the proctor before they leave and they are not allowed to return to continue the exam.

The only materials that the students are allowed to have on their desks immediately before the examination are:  blue or black ballpoint pen, pencil, eraser, ruler, compass, and protractor.  All other items such as notes, books, cellular phones, etc. are not allowed on your desks, but these may be placed in a designated area in the room.  Calculators are not allowed.

2016 ACM-ICPC Philippines Southern Luzon

slic2016

I was a problem setter and judge for the 2016 ACM-ICPC Philippines Southern Luzon Invitational Contest held last October 1, 2016 at the Ateneo de Naga University.

The winning team was from the University of the Philippines, Los Baños. It solved 7 of the 12 problems. (The teams were given 5 hours.) The results are shown below. (The image has been slightly edited.)

standings

If I’m not mistaken, the warm-up problems were the same as last year’s.  The contest problems are here. I provided two contest problems: “C” (Billiard Paths 1) and “H” (Billiard Paths 2).  (My slides explaining my solutions are here and here.) As you can see from the scoreboard below, two teams attempted problem “C” (and both succeeded), and no team attempted problem “H.”

I was also a problem setter and judge in 20152014, and 2013.

19th Philippine Mathematical Olympiad

The Philippine Mathematical Olympiad, a nationwide mathematics competition open to all junior and senior high school students of the Philippines, is carried out in three stages.

The qualifying stage (to be held on October 22, 2016, Saturday) consists of a written exam administered in fourteen (I think) regional testing sites. The exam consists of fifteen multiple-choice questions worth 2 points each, ten multiple-choice questions worth 3 points each, and five answers-only questions worth 6 points each.

The area stage (to be held on November 19, 2016, Saturday) consists of a written exam administered in testing sites for the four areas (Luzon, Visayas, Mindanao, and National Capital Region). The exam consists of twenty answers-only questions and three open-ended questions that require full solutions.

The national stage (to be held on January 21, 2017, Saturday) consists of a written exam and an oral exam administered in Metro Manila. The written exam consists of four open-ended questions that require full solutions to be answered in 4.5 hours. The oral exam (which is open to the public) consists of 30 questions read to the participants and to be answered within a specified time for each item.

Each school may send up to twenty participants (students with a final grade of 88% (or its equivalent) in mathematics in the previous school year). The participants with the top fifty scores in the qualifying stage per area will qualify for the area stage. The participants with the top twenty scores (national ranking) in the area stage will qualify for the national stage. The national finalists will be qualified to join the International Mathematical Olympiad Summer Camp (IMOSC). The representatives of the country to the International Mathematical Olympiad will be selected from the participants of the IMOSC.

A copy of the Department of Education Advisory number 244, series of 2016 about the 19th PMO is here.

I am the regional coordinator for Region V (Bicol Region). Schools in Region V that are interested in participating should complete the official application form and submit it to me on or before 12:00 noon of September 23, 2016 (Friday). My contact information can be found in the official brochure.

2015 ACM-ICPC Philippines Southern Luzon

icpc2015 I was a problem setter and judge for the 2015 ACM-ICPC Philippines Southern Luzon Invitational Programming Contest held last September 13, 2015 at the Ateneo de Naga University.

The winning team was from Ateneo de Naga University. It solved 5 of the 10 problems. (The teams were given 5 hours.) The results are shown below. (The image has been slightly edited. Click on it to see a higher-resolution version.)

The warm-up problems are here and the contest problems are here. I provided two contest problems: “D” (Freeway Traffic) and “I” (Forest Fire Spread). They are both about cellular automaton models.

I was also a problem setter and judge in 2014 and in 2013.

ACM ICPC Bicol 2014

10649866_512300605568241_2964989848509910029_n I was a problem setter and judge for the ACM ICPC Philippines 2014 National Programming Contest held last September 6, 2014 at the Ateneo de Naga University. (I was also a problem setter and judge in last year’s multi-provincial programming contest.)

There were 31 teams from 13 schools. The winning team was from Ateneo de Manila University. It solved all 10 problems in a little less than 2 hours. (The teams were given 5 hours.) The detailed results are here.

I provided two problems: “B” (Scrabble) and “H” (Boggle). My Scrabble problem was one of the easiest (26 teams answered it correctly) and my Boggle problem was one of the hardest (7 teams answered it correctly).

ACM ICPC Bicol

acmicpcb I was a problem setter and judge for the ACM ICPC Bicol held last August 10, 2013 at the Ateneo de Naga University. Programming was done using C, C++, or Java and judging was done using PC2. There were 32 teams from 15 schools (of these, 4 teams were from 2 schools outside the Bicol region). The winning team was from Ateneo de Manila University and solved all 10 problems in the given 5 hours. A team from Ateneo de Davao University finished in second place with 5 problems solved. (The detailed results are here.)

I provided two problems: “F” (Sharkovski’s Ordering) and “I” (Interior Lattice Points). The first was inspired by a 2008 paper by Ciesielski and Pogoda and the second by chapter 5 of Ian Stewart‘s Another Fine Math You’ve Got Me Into… (New York: W. H. Freeman and Company, 1992).

Problem “F” looks easy (16 teams tried to answer it) but implementing the solution could be a little tricky (only 5 got it correctly). Problem “I” looks difficult (2 teams tried to answer it) but implementing it is not so hard if you know Pick’s Theorem (both teams got it correctly the first time).

Regional Elementary Schools Press Conference

Last February 5, 2013, my daughter participated in the (Region V) Regional Elementary Schools Press Conference at the Sto. Domingo Central School in Sto. Domingo, Albay.

According to the Department of Education Region V Regional Memorandum no. 4, s. 2013,

With the theme, Campus Journalists: Championing Ethics in Social Media, the Conference aims to:

  1. promote understanding among campus journalists/participants the importance of journalism by expressing it through different journalistic endeavors and approaches;
  2. sustain advocacy on social consciousness;
  3. provide a venue for an enriching learning experience for pupils interested in pursuing journalism as a career;
  4. promote responsible journalism and fair and ethical use of social media; and
  5. enhance journalistic competence through healthy and friendly competitions.

She joined the individual contest in feature writing (English category), where the participants were asked to write about their personal experiences with social media.
