In POW 2013-19, there was a typo in the assumption on \( a_1, \dots, a_{27} \). The inequality is now corrected to the equality.
There will be no POW this week due to 추석 (thanksgiving) break. POW will resume next week.
POW will resume on Apr. 28.
There were no correct solution submitted by the due (Friday 3pm). Since we received a correct solution a few hours after the due, we decided to extend the due by Apr. 14, 3pm. Any solution submitted by that due will be considered for the full credit.
POW 2023-02 is still open. (Only a partial solution has been submitted.) Anyone who first submits a correct (full) solution will get the full credit.
POW 2022-20 is still open. Anyone who first submits a correct solution will get the full credit.
POW will resume on Oct. 28.
POW 2022-10 is still open. Anyone who first submits a correct solution will get the full credit.
POW 2022-02 is still open. Anyone who first submits a correct solution will get the full credit.
This semester, the rule is changed so that the solutions are due next Friday at 3PM, i.e., exactly a week after the post of the problem.
