At the two campuses of St. John's College, U.S. and a few other American colleges with a similar version of the Great Books program, a "tutorial" is a class of 12–16 students who meet regularly with the guidance of a tutor. The tutorial focuses on a certain subject area (e.g., mathematics tutorial, language tutorial) and generally proceeds ...
Just as the class P is defined in terms of polynomial running time, the class EXPTIME is the set of all decision problems that have exponential running time. In other words, any problem in EXPTIME is solvable by a deterministic Turing machine in O (2 p ( n ) ) time, where p ( n ) is a polynomial function of n .
Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

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.
Although the three-peg version has a simple recursive solution long been known, the optimal solution for the Tower of Hanoi problem with four pegs (called Reve's puzzle) was not verified until 2014, by Bousch. [20] However, in case of four or more pegs, the Frame–Stewart algorithm is known without proof of optimality since 1941. [21]
The first known solution to complete enumeration was posted by QSCGZ (Guenter Stertenbrink) to the rec.puzzles newsgroup in 2003, [11] [12] obtaining 6,670,903,752,021,072,936,960 (6.67 × 10 21) distinct solutions.
In computational mathematics, an iterative method is a mathematical procedure that uses an initial value to generate a sequence of improving approximate solutions for a class of problems, in which the i-th approximation (called an "iterate") is derived from the previous ones.
