Problem Collection for Bulgaria

History and System

Mathematical competitions in Bulgaria have been held since 1950, skipping 1958 and 1959. The system didn’t change since 1962, when the fourth round of National Olympiad was introduced. An official competition season consists of four rounds of the national olympiad and Winter and Spring competition. Third and fourth rounds are usually held in April and May, respectively.

Bulgaria at International Competitions

Bulgaria has participated at IMO and Balkan MO since their foundations (1959 and 1984, respectively) with distinguishable performances. In the recent history, the best success of a Bulgarian team on an IMO is the 1-st place at IMO 2003, when they left the runner-up China far behind. The team for international competitions is today selected through (three?) selection exams during May and June.
