سيُعقد في Bremen بريمن الألمانية في الفترة الممتدة من العاشر إلى الثاني والعشرين من شهر جويلية 2009 الأولمبياد الخمسين للرياضيات الذي يضم طلاب المدارس الثانوية وعلماء وموهوبين في الرياضيات، وتقام هذه الدورة مرة كل عام، وقد كانت الدورة الأولى سنة 1959 حيث أقيمت برومانيا بسبع دول فقط... فزادت تدريجيا إلى أن أصبحت بأكثر من تسعين دولة ومن مختلف قارات العالم، وفي رسالة الأولمبياد التي كتبت باللغتين الألمانية والإنجليزية يسعى القائمون على إلى تشجيع المواهب الشابة وإعطاءهم فرصة التطوير بنجاح، وإقامة صداقات جديدة ومحفزات خاصة للأجيال القادمة.
وستكون الجزائر حاضرة بستة أعضاء (إداريان، وأربعة منافسين):
رئيس الوفد: عبد الصديق بوشوبة.
نائب رئيس الوفد: علي عطية.
المنافس الأول: لامية عطوش (16 سنة).
المنافس الثاني: حسن زلاسي (18 سنة).
المنافس الرابع: قاسم حريز (18 سنة).
المنافس الثالث: أسامة قصاب (19 سنة).

ولتعريف القارئ أكثر حول هذه الدورة نقدم له هذه التعريف الموجز حول الأولمبياد:
بطولة أولمبياد الرياضيات هي بطولة عالمية تهتم بالمسابقات في الرياضيات، وهي موجهة خصيصا لطلاب المدارس الثانوية، عقدت أول دورة في رومانيا سنة 1959 بحضور سبع دول، وهي: المجر، وبلغاريا، بولندا، تشيكوسلوفاكيا (بعد الموافقة على التقسيم سنة 1992 أصبحت هناك دولتان، هما: التشيك وسلوفاكيا)، ألمانيا الشرقية (للعلم فقد اتحدت الألمانيتان فأصبحت ألمانيا واحدة بسقوط جدار برلين سنة 1989)، والاتحاد السوفيتي (روسيا، فلا يوجد حاليا اتحاد سوفييتي بعد التقسيم وتشتت الجمهوريات الخمسة عشر سنة 1991)، ومنذ ذلك الوقت وإلى يومنا هذا أصبحت الدورة سنوية.

حدد عدد المشاركين كحد أقصى بستة (قائد ونائب، وأربعة طلاب)، ولا يجب على المشارك أن لا يتجاوز عمره العشرين سنة لكنه يستطيع أن يشارك بعدد غير محدود من المرات، وأن لا يملك أية وظيفة في ثانويته.

تكون المسابقة بورقتي أسئلة يوميا كل ورقة تحتوي على ثلاث أسئلة، وتبلغ قيمة كل سؤال سبع علامات... هذا ويمكن لأية دولة مشاركة أن تحضر ست أسئلة للمسابقة النهائية وتعرضها على لجنة التحكيم.

What is the IMO?
The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students. The first IMO was held in 1959, hosted by Romania, with seven countries participating: Hungary, Bulgaria, Poland, Czechoslovakia, East Germany and USSR. Since then, it has been held with each participating country hosting it in turn.The number of participating countries increased to 97 countries from all continents in the 49th IMO.

When the IMO first began, each country was allowed up to eight participants. In 1982, this was scaled back to four members, but in 1983 the number was increased to six, which is where it still stands. The contestants must be no more than 20 years old and must not have any post secondary-school education. There is no limit to how many times a person may participate in the IMO, provided the individual meets the age and schooling requirements. The usual size of an official delegation to an IMO is (a maximum of) six students, along with the Leader and Deputy Leader. The student competitor writes two papers, on consecutive days, each paper consisting of three questions. Each question is worth seven marks. Only a whole number of marks are given, so there can be no half mark score.

Each invited country can send in up to six questions for consideration for the final competition papers. These submissions are reviewed by the host country's problem selection committee, and a short list of about thirty questions is made. The choice of the questions on the actual competition papers is made by the International Jury. The International Jury consists of the Chief Delegate (Leader) from each participating country, together with the Chairman named by the host country. Decisions are made by a simple majority vote. The official languages of the IMO are English, French, German and Russian. Since Spanish is spoken in a large number of participating countries, it has become an unofficial “official” language. In recent years, English has been the working language of the International Jury, with the other official languages available whenever required.

The International Jury members receive the short list of questions on arrival at the sequestered site. They have little time to review these problems before meeting to discuss which problems will be included. An honour system requires delegates to identify any suggested problems that are well known, in text books, or have been used in training programs. Some problems are eliminated as too easy or too hard. After considerable debate, the six problems are chosen, and their wording in all the official languages is agreed. The leaders of countries, whose students require other languages, then translate the questions into the required language. After that all papers, in all languages, are inspected by all members of the International Jury, to ensure that all translations are appropriate.

When all papers are prepared the Deputy Leaders and Contestants will arrive at the venue. The Opening Ceremony is held, and the Contest begins the following day to last for two days. Each Contestant has to answer 3 questions within 4½ hours in each of the two days in his/her own language. After the Contest, the programme shifts to entertainment such as sightseeing and games, for three days. During this period, the Contestants will have good opportunities to develop international friendship, through sharing talks and entertainment with each other. Meanwhile, the Leaders and Deputy Leaders mark the exam papers, and hold Coordination sessions to discuss whether the marking has been done fairly and correctly.

The last day is for the Closing Ceremony, and the Gold, Silver, and Bronze medals will be awarded for excellent performances. The International Mathematical Olympiad is an individual competition. Only individuals compete. There is no team competition. Medals are awarded to approximately the top half of the participating students. Gold, Silver and Bronze medals are awarded in the ratio of 13, with no more that 1/12 of the students getting a Gold Medal, no more that 1/4 of the students getting either a Gold or a Silver Medal and no more that 1/2 of the students getting a medal of any kind. In order to encourage more students, and to encourage students to solve complete problems, recent practice has awarded a Certificate of Honourable Mention to any student (not receiving a medal) who obtained full marks for at least one problem.
