According to the IChO rules the relative weights of the theoretical and practical problems has the ratio 40:60. It was decided by the jury that this could be accomplished by giving each problem a specified number of red points adding up to 40 and 60 in each cathegory. The blue points were used to determine the relative weight of each sub-question within each problem.

Below you will find hypertext versions of all problems presented at the 26th IChO.

Note : It is not possible to present formulas correctly in hypertext . Some (not all !) of the formulas are presented as gif-mages. So you will need a viewer that can handle images to to look at the formulas. The best way to look at the problem texts is to copy the rtf-versions to your computer and import them into to your own text-editor (MS Word f.ex.).
