The GA members can either accept or, in case of major ambition, form other serious reasons, deny the proposals by voting. When and if a proposal is made, another prepared proposal will be offered to the GA. For such cases, the Scientific Committee should prepare at least two extra proposals for each round.

The selected problems will be translated by the team leaders into the native languages of the teams.
The Scientific Committee (SC) is a chairperson and a number of experts (SC members) from the host country. It becomes active well before the beginning of the Olympiad and has the task of selecting and preparing problem proposals. A further task of the Scientific Committee is to test and evaluate the solutions of the contestants.
The competition consists of two rounds in two days. In both rounds the working time is five hours and the contestants will be given three problems to solve. The selected problems will be translated by the team leaders into the native languages of the teams. Contestants may submit written questions to the Scientific Committee on the formulation and interpretation of problems during the initial period of each competition round. Contestants may use their native language when asking questions; further details will be regulated by each year's competition rules.
The host country publishes competition rules that include the description of the competition environment and details of the competition at least one before CEOI starts. No special hardware requirement or software packages will be needed to solve the problems. The whole communication between the CEOs and the contestants will be in a written form.
When the working time is over, the solutions of each of the contestants will be checked by an evaluator. The evaluation is based on the test data and responses of the programs only. The evaluation procedure is concluded with the meeting of the Scientific Committee, where the evaluation reports are discussed. Potential disagreements are dissolved by voting. Achieving and proper and balanced evaluation is the responsibility of the Scientific Committee. If a team leader does not accept the results of the evaluation, he / she may appeal to the General Assembly. Finally, the president of SC or IC presents the anonymous results to the General Assembly.
