SBU CE-CS-Math Team Finishes Fourth in GNYR 2018!

Stony Brook's top team (SBU-Ereshkigal) consisting of three students from Computer Engineering, Computer Science and Mathematics finished 4th in the 2018 ACM ICPC Greater New York Regional Programming Contest held at Manhattan College on November 19 this year. They finished behind one team from Columbia, Princeton, and Cornell each and ahead of everyone else including the remaining three teams from Princeton, four from Cornell, three from Yale, one from Columbia, four from NYU, one from Rochester, and three from Rutgers. Stony Brook's other teams were ranked 20th, 26th, and 37th among 68 participating teams.

Columbia University team Columbia-Kington has become the regional champions this year and earned a trip to the 2019 ACM World Finals to be hosted by the University of Porto, Portugal in Spring 2019. The final rank list of the top 20 teams is shown above. The full final standings can be found here.

There were ten algorithmic programming problems to be solved by teams of three in no more than five hours using a single computer. The problems along with the judges' solutions and judges' input/output data can be found here. This year's problems were harder than the problems set in the recent past. There were two problems (B and I) that no one could solve, and one problem (I) that no one even attempted.

Stony Brook's team SBU-Ereshkigal of Jiarui Zhang (Computer Engineering), Junxiang Huang (Computer Science), and Taras Kolomatski (Mathematics) finished in 4th place among 68 teams. Their final standings, however, do not tell the entire story of what happened during the contest. Approximately two hours into the contest they were leading the points table with 5 problems solved (see the scoreboard snapshot below) when no other teams solved more than 4. They were the second team to solve 6 problems, and the third to solve 7. They almost solved problem B (Moving Building) — their 8th problem. They found a small bug in their solution toward the very end of the contest, but ran out of time before they could submit the fixed solution. Their final bug-fixed solution matched judges' output when run on the publicly released judges' input data. No team managed to solve problem B during the contest. The last problem solved by the top two teams (Columbia-Kington and Princeton 1) was problem D (Tanks and Pipes) — they did not attempt problem B. SBU-Ereshkigal instead concentrated on problem B during the final hour of the contest and did not attempt problem D.

Standings after 1 hour and 50 minutes into the contest Standings after 2 hours and 53 minutes into the contest
Top 20 Teams after Approximately Two Hours into the Contest:
SBU-Ereshkigal is leading with 5 problems solved!
Top 20 Teams after Approximately Three Hours into the Contest:
SBU-Ereshkigal is in 2nd place with 6 problems solved!

Stony Brook team SBU-Artemis of Sudharsan Kumar, Harsh Ranjan, and Mehul Jain (all CS students) finished in the 20th place with 4 problems. Team SBU-Cantor of Shawn Mathew, Yuren Huang, and Gaurav Ahuja (all CS students) was ranked 26th with 3 problems.

Team SBU-Janus consisted of the two youngest SBU contestants Daniel DeLayo (Sophomore, CS and Physics) and Giorgian Borca-Tasciuc (Sophomore, CS and CE) led by CS student Allen Kim. They submitted solutions for 5 problems but got only one accepted during the contest time. But SBU-Janus is our developmental team with an eye to the future. This was Daniel and Giorgian's first contest experience outside SBU. Allen has been an excellent mentor for them, and with his (and our coaching team's) continued guidance we expect them to excel in the future.

One member of SBU-Ereshkigal (Junxiang Huang), all three members of SBU-Artemis (Sudharsan Kumar, Harsh Ranjan, and Mehul Jain), and two members of SBU-Janus (Daniel DeLayo and Giorgian Borca-Tasciuc) will be eligible to represent Stony Brook again next year.

Stony Brook teams were trained by CS PhD students Haochen Chen and Zafar Ahmad with inputs from faculty advisor (and coach) Rezaul Chowdhury. Both Haochen and Zafar are veteran competitive programmers. Haochen is also an ACM World Finalist. They were instrumental in the success of Stony Brook's pre-regional local selection contest this year which was sponsored by Google. All contest-related activities were undertaken with generous support from the Department of Computer Science.
