On the first day participants will be asked to solve three problems. For at least one of the problems its complexity will not depend on the algorithm, but on the field from which the problem is drawn. On the second day participants will be asked to solve a single, complex problem of an algorithmic nature. The problems will be chosen by the jury from the problems that have been prepared by the Scien tific Committee and will be selected from the problems submitted by the participating countries. No special hardware requirements or software packages (e.g. no graphic packages) will be needed for solving problems. The problems are given to the students in written form, without any additional oral information. The following programming languages are permitted: * Turbo Pascal V. 6.0, * Turbo C++ V.2.0 * Quick Basic V.4.5 * LCN Logo V.3.0 Should participants wish to use any other language or version, delegation leaders should consult the organizers in writing as early as possible, but no later than 1 June 1993. Tools For the Olympiad each participant will be provided with a personal computer with a USA style, 101-key, QWERTY keyboard and the necessary software. MS-DOS V. 5.0 will be provided. The compilers and programming environments for the above mentioned programming languages as well as the MS-DOS editor will be installed on hard disk. Hard copies of files can only be printed off-line via diskettes. Only the computers provided may be used in the competition. No copying of the software on the computers, nor the use of private or other software or private diskettes will be allowed. The use of printed material will not be restricted. Working Languages Every participant may use his/her mother tongue. The problems will be given in both English and the respective mother tongues.

On the first day the Jury will select three problems; one each from three groups. On the second day the Jury will select one of the three problems submitted. The selected problems will be translated by the delegation leaders into the respective mother tongues. At 10.00 am the problem(s) will be given to the participants in English and in their mother tongues. Five hours' working time will be allowed. During the first half hour a participant may ask the jury in writing about the text of the problems. Only questions that can be answered with "Yes", "No" or "No comment" will be accepted. The answers will be given as soon as possible. When the working time has elapsed, each participant's program will be checked by a coordinator, using previously unknown test data. The delegation leader and the student must be present. During this checking, all required tests will be run and a written report will be signed by the coordinator and the delegation leader. Each participant's program will be copied on two diskettes. The coordinator and the delegation leader will each keep one copy of the diskettes. Printouts will be produced by the coordinator and then given to the delegation leader. The delegation leader and the coordinator together will examine each solution and agree on a preliminary evaluation. By moderating the evaluation, Coordinating Committee will ensure a just and balanced evaluation is achieved. The chief coordinator will present the results to the jury, who will make the final decision. If a delegation leader can not accept the coor dinating committee's evaluation, he may address himself to the jury. All decisions taken during the evaluation procedure will be final. When the evaluation is finished, the Jury will determine the minimum scores for the gold, silver and bronze medals. The number of winners of these medals is to be in the proportion 1:2:3, with up to half the participants receiving medals. Each competitor will receive a certificate of participation. The medals, certificates and other prizes will be awarded at an official ceremony. Schedule October 16th. - 25th. 1993 Saturday 16 Arrival. Sunday 17 Late arrival. Excursion (day).
