Appendix Table A5 | Codeforces per-problem results. Problems on Codeforces are grouped into
contests, and uniquely identiﬁed by their contest and problem letter. For each solved problem, we
specify whether they were solved (1 for solved), how many incorrect submissions there were before a
correct one, and the simulated submission time in minutes. Unsolved problems are not listed. Results
corresponding to the three evaluations are separated by commas. “-” indicates that the problem in
the evaluation was unsolved. Submitted programs can be found on our 3 accounts on Codeforces:
SelectorUnlimited, WaggleCollide, and AngularNumeric. Note that for the ﬁrst evaluation, we only
submitted at most 10 times per problem. Unsolved problems and submissions beyond 10 (for the
second and third evaluations) are marked in red to indicate that they are not included when measuring
performance in the setting with a maximum of 10 submissions per problem.
