The Indian Olympiad Qualifier in Mathematics (IOQM) is a national exam for students in grades 8-12. It's used to shortlist students for HBCSE's Mathematical Olympiad program. Students must be under 20 years old by June 30 of the IMO year and cannot have passed Class 12.
The cutoffs (minimum scores required to receive a gold, silver, or bronze medal respectively) are then chosen so that the numbers of gold, silver and bronze medals awarded are approximately in the ratios 1:2:3. Participants who do not win a medal but who score 7 points on at least one problem receive an honorable mention. [18]

In Singapore, the SMO (Singapore Mathematical Olympiad) is held with three sections- Junior (Grade 7 and 8), Senior (Grades 9 and 10) and Open (Grades 11 and 12). There are two rounds in each of the competitions and the top 20 SMO (Open) Round 2 scorers will be invited to attend IMO training sessions, from which two IMO-style National Team ...
The problem of points, also called the problem of division of the stakes, is a classical problem in probability theory.One of the famous problems that motivated the beginnings of modern probability theory in the 17th century, it led Blaise Pascal to the first explicit reasoning about what today is known as an expected value.
Given the two red points, the blue line is the linear interpolant between the points, and the value y at x may be found by linear interpolation.. In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points.
Using the "elbow" or "knee of a curve" as a cutoff point is a common heuristic in mathematical optimization to choose a point where diminishing returns are no longer worth the additional cost. In clustering, this means one should choose a number of clusters so that adding another cluster doesn't give much better modeling of the data.
The Banach fixed-point theorem (1922) gives a general criterion guaranteeing that, if it is satisfied, the procedure of iterating a function yields a fixed point. [2]By contrast, the Brouwer fixed-point theorem (1911) is a non-constructive result: it says that any continuous function from the closed unit ball in n-dimensional Euclidean space to itself must have a fixed point, [3] but it doesn ...
