VOJ ALGORITHMIC TEAM

Valladolid Online judge is growing fast. It has over 2.000.000 submissions of more than 38000 users, and over 1500 problems available...Things to do on the judge also increased fast, we had to made more problems for people to solve and ensure that every data set was good enough to reject every wrong solutions. We also had to find and solve every little mistake on the problems, descriptions, etc. We were overload.

That's why we decided to ask users for help. They kindly accepted our invitation to help us keeping the judge as complete and right as it should be. In the first few days they did more than we could do in a month! So we decided to make an "algorithmic team", a group of people that make the judge update everyday. They would answer any clarification, problem or suggestion you might have. They'll be spending their time in helping us in making people discover the secrets of computering contests.

This site is for them, that's my way of saying:

¡Thank you!
