Competitive programming is recognized and supported by several multinational software and Internet companies, such as Google, [1] [2] and Meta. [ 3 ] A programming competition generally involves the host presenting a set of logical or mathematical problems , also known as puzzles or challenges, to the contestants (who can vary in number from ...
The first Project Euler problem is Multiples of 3 and 5. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. It is a 5% rated problem, indicating it is one of the easiest on the site.
MathOverflow is a mathematics question-and-answer (Q&A) website, which serves as an online community of mathematicians. It allows users to ask questions, submit answers, and rate both, all while getting merit points for their activities. [1] It is a part of the Stack Exchange Network, but distinct from math.stackexchange.com.
Figure 1. Finding the shortest path in a graph using optimal substructure; a straight line indicates a single edge; a wavy line indicates a shortest path between the two vertices it connects (among other paths, not shown, sharing the same two vertices); the bold line is the overall shortest path from start to goal.
Block scheduling or blocking is a type of academic scheduling used in some schools in the American K-12 system, in which students have fewer but longer classes per day than in a traditional academic schedule. It is more common in middle and high schools than in primary schools.
The Russian School of Mathematics (RSM) is an after-school program based in North America that provides mathematics education to children attending K–12 public and private schools. The school provides children with the opportunity to advance in mathematics beyond the traditional school curriculum. The founder of RSM is Inessa Rifkin and the ...
In this permutation graph, the maximum cliques correspond to the longest decreasing subsequences (4,3,1) and (4,3,2) of the defining permutation. Planar graphs , and other families of sparse graphs, have been discussed above: they have linearly many maximal cliques, of bounded size, that can be listed in linear time. [ 18 ]
