TCO 2019 Algorithm Rules The rules for advancement to the onsite finals of TCO 2019 Algorithm have changed from those for TCO 2018: http://tco19.topcoder.com/home/algorithm/algorithm-rules This page claims there are "three (3) ways to advance to the Onsite Finals"! The first way to advance is to take part in SRMs. There are four three-month Online Stages, during which every positive score in an SRM counts towards a global ranking. The best competitor in each Online Stage advances to the onsite finals directly, with the next 10 competitors advancing to Online Round 4 (which is the final qualification round). The other two ways stay the same. The best 10 competitors (used to be 14 though) advance from Online Round 4, and the best 2 competitors advance from Online Wild Card Round. The changes seem to be big enough -- and already relevant, since SRM 736 on August 15 (in two days from now) already counts towards Online Stage 1. However, apart from TCO 2019 website I've only seen this information in T...

Problem Writers: TCO19 Problem Writing Trip Opportunity Last year we had launched a problem writing Trip to 2019 TCO Finals. However, after feedback from the community and writers particularly, we have decided to increase the number of trips and also make it simple for you to earn a trip. We now have 5 trips to 2019 TCO Finals and 5 Trips to 2019 TCO Regional Events. With 100 points, you can win a trip to the 2019 TCO Finals (location to be revealed later in the year)and with 65 points you can win a trip the nearest regional to your location. You can submit your problems and earn points during any stage of TCO. All problems must be submitted correctly via the process explained here by midnight (12:00 am) Eastern time on the final day *__Points__* | Point Allocation | Easy | Medium | Hard | | ---------- | ---------- | ---------- | ---------- | | SRM Div 2 | 2 | 3 | 5 | | SRM Div 1 | 5 | 10 | 20 | *__Trips__* | Trips* | Number of Trips | Points Requ...

TCO 2019 marathon — ? I'm not sure what's exactly happening right now. I know that a few (about 7) last SRMs was a series of fuck-ups, so I assume that people from marathons also aren't sure what should be done now. Can anybody from topcoder write any clarification? We've been waiting more than two weeks for the systests for the first round (if I'm not mistaken). Are the current standings final? Is there any way to be informed about the news and know the current status? [There](https://tco19.topcoder.com/marathon/marathon-rules)'s some information that you wanted to make three stages of standard matches and three matches in each of them. Why is leaderboard showing stages numbered $2$, $3$ and $4$ and the fact that stage "$3$" had only two matches and stage "$4$" still had no matches... I'm not sure if the stage "$1$" is missing, or if you didn't manage to organize matches in stage "$4$". Or maybe just the leaderboard doesn't work? It would be nice to check stage dates in the "rules" section, but they ...
