Hello, Codeforces!

We are pleased to announce the 3rd Hello Barcelona Programming Bootcamp in collaboration with Moscow Workshops ICPC, organised by Harbour.Space University with content provided by Moscow Workshops ICPC, in collaboration with Moscow Institute of Physics and Technology, ITMO University, Saint Petersburg State University and Codeforces!

The boot camp will be held from 26 September to 4 October, 2018 in Barcelona, and hosted at the beautiful and technologically mind-bending Media-TIC building — the Smart Building of Tomorrow.

The world's greatest coaches training the participants of Moscow Workshops ICPC events will be attending the programming bootcamp: Mike MikeMirzayanov Mirzayanov, Andrey andrewzta Stankevich, Michael Endagorion Tikhomirov, Gleb GlebsHP Evstropov, Artem VArtem Vasilyev, Ivan ifsmirnov Smirnov and other world renowned Russian coaches. The Chief Judge of the camp is Oleg snarknews Khristenko. It will be an important opportunity for teams from all over the world to learn from these well-known and successful coaches in the ICPC world.

“The participants are facing the problems from real contests selected by our coaches. In competitive programming it’s very important to have real solving experience: one thing is to be able to solve problems staying in comfortable environment of one’s university but championships are completely different. The only way to get ready for the extreme conditions of ICPC is to visit our programming boot-camps”, says Alexey Maleev, the founder of Moscow Workshops ICPC.

So how do you get the most out of the camp? "I think there is no universal solution for "get the most out of a camp" – everyone should find their own path, but the general guideline will be: communicate with other participants as much as you can, make sure you do upsolving (at least some), keep track of how much you sleep," says Gleb GlebsHP Evstropov, coach.

A look back on our recent boot camp:

“Having visited all the Hello Programming Bootcamps, I left the events feeling inspired from the overall atmosphere. I am sure that all teams received an immense amount of knowledge and skill. As one of the coaches, all of the flattering reviews about the camp from the participants were pleasant for me to hear. I am very glad that these camps are becoming regular. Harbour.Space University and Moscow Workshops ICPC have done a job worthy of admiration!” says Mike MikeMirzayanov Mirzayanov.

The Bootcamp will be split into three divisions:

• Division A. Designed to prepare students to excel and win medals in the next ICPC World Finals.
• Division B. Designed to help teams prepare for the next season of ICPC Regionals and international competitions. This is an appropriate introduction for teams and students new to the world of ICPC and competitive programming competitions in general. The Division B curriculum features thematic lectures and contests.

The participation fee is unchanged: €1270 per person (cultural programme, accommodation and half-board meals included). Single participants and teams must register before July 1st, 2018 to receive the 15% off Early Bird Discount, or the 20% off Loyalty Discount, which is awarded to teams that participated in previous Hello Programming Bootcamps or Moscow Workshops ICPC boot camps.

Thank you for taking part in the 2nd Hello Barcelona Programming Bootcamp in collaboration with Moscow Workshops ACM ICPC. It was a pleasure to have you on board. We hope you enjoyed it and we would love to have you back next time.

Congratulations ITMO and Harbour.Space University teams for winning divisions A and B! It was amazing watching the scoreboard throughout all nine days as teams from New South Wales, Saint Petersburg, Tokyo, among many others, challenged the top spots. Watch the recap here!

``Geometry is the key to success in modern contests'' states Andrey Stankevich, coach of 7 ACM-ICPC World Champions

Lecturing both divisions A and B, Andrey brought a vast wealth of knowledge to the boot camp, and shed light on how to better tackle the problem sets that teams will face in their upcoming regional competitions.

“What technology should we use to analyze big data?” asks Alexey Dral, Head of Data Science School at Corporate University of Sberbank

Leisure day was a full one, with bus city tours, to gaming, to lectures and workshops. We had many special guests Sberbank, including Alexey Dral, who talks about the impact of a boot camp that is not only focused on the coding aspect, but the machine learning, the data processing and the practices that each participant can utilise to become an ACM-ICPC competitor to be reckoned with.

The world's greatest coaches will be attending: Andrew andrewzta Stankevich, Michael Endagorion Tikhomirov, Gleb GlebsHP Evstropov, Artem VArtem Vasilyev and other world renowned Russian coaches. As a coach, I will come too. The Chief Judge of the camp is Oleg snarknews Khristenko. Seriously, it will be a unique opportunity for teams around the world to learn from such well-known and successful coaches in the ACM-ICPC world.

Having visited the first Hello Barcelona programming Bootcamp in February, I left the event feeling inspired from the overall atmosphere. I am sure that all teams received an immense amount of knowledge and skills. As one of the coaches, all of the flattering reviews about the camp from the participants were pleasant for me to hear. I am very glad that these camps are becoming regular. Harbour.Space University and Moscow Workshops ACM ICPC have done a job worthy of admiration!

The Bootcamp will be split in two divisions:

• Division A. Designed to prepare students to excel and win medals in the next ACM-ICPC World Finals.

• Division B. Designed to help teams prepare for the next season of ACM-ICPC Regionals and international competitions. This is an appropriate introduction for teams and students new to the world of ACM ICPC and competitive programming competitions in general. The Division B curriculum features thematic lectures and contests.

The participation fee is unchanged: €1270 per person (cultural program, accommodation and half-board meals included).

Single participants and teams must register by July 1st, 2017 to receive the 15% off-Early Bird Discount, or the 20% off-Loyalty Discount, which is awarded to teams that participated in previous Moscow Workshops ACM ICPC boot camps.
