Casp stands for Critical Assessment of Structure Prediction. It is a competition that helps scientists make better computers to predict the structure of proteins. Proteins are like building blocks for the body and understanding how they work is important for finding new cures for diseases.
In the competition, scientists from all over the world make computers that try to predict the shape of proteins based on the information given to them.
The scientists then submit their computers to the competition and the computers are tested to see which one did the best job of predicting the structure of the proteins.
The winner of the competition is the computer that did the best job each year.
