The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré conjecture at the ...
The two solutions with the vertical axis denoting time, s the start, f the finish and T the torch The bridge and torch problem (also known as The Midnight Train [1] and Dangerous crossing [2]) is a logic puzzle that deals with four people, a bridge and a torch.
In the set cover decision problem, the input is a pair (,) and an integer ; the question is whether there is a set cover of size or less. In the set cover optimization problem , the input is a pair ( U , S ) {\displaystyle ({\mathcal {U}},{\mathcal {S}})} , and the task is to find a set cover that uses the fewest sets.
Tests of Engineering Aptitude, Mathematics, and Science (TEAMS) is an annual competition originally organized by the Junior Engineering Technical Society (JETS). TEAMS is an annual theme-based competition for students in grades 9–12, aimed at giving them the opportunity to discover engineering and how they can make a difference in the world.
Recall that [Ω] is the angular velocity matrix. The matrix [S] is an element of the Lie algebra se(3) of the Lie group SE(3) of homogeneous transforms. The components of [S] are the components of the twist screw, and for this reason [S] is also often called a twist.
The nearest neighbour algorithm was one of the first algorithms used to solve the travelling salesman problem approximately. In that problem, the salesman starts at a random city and repeatedly visits the nearest city until all have been visited.

The first three stages of Johnson's algorithm are depicted in the illustration below. The graph on the left of the illustration has two negative edges, but no negative cycles. The center graph shows the new vertex q, a shortest path tree as computed by the Bellman–Ford algorithm with q as starting vertex, and the values h(v) computed at each other node as the length of the shortest path from ...
