Can 3SUM be solved in strongly sub-quadratic time, that is, in time O(n 2−ϵ) for some ϵ>0? Can the edit distance between two strings of length n be computed in strongly sub-quadratic time? (This is only possible if the strong exponential time hypothesis is false.) Can X + Y sorting be done in o(n 2 log n) time?
This is a balanced assignment problem. Its solution is whichever combination of taxis and customers results in the least total cost. Now, suppose that there are four taxis available, but still only three customers. This is an unbalanced assignment problem. One way to solve it is to invent a fourth dummy task, perhaps called "sitting still doing ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
A decision problem has only two possible outputs, yes or no (or alternately 1 or 0) on any input. Decision problems are one of the central objects of study in computational complexity theory. A decision problem is a type of computational problem where the answer is either yes or no (alternatively, 1 or 0).
American Airlines has settled a racial discrimination lawsuit filed by three Black men who alleged they were thrown off a plane in January for a false complaint about body odor.
Nearly two years ago, NFL fans watched in horror as Buffalo Bills safety Damar Hamlin collapsed on the field after experiencing a sudden cardiac arrest (SCA) midgame. But the now-26-year-old ...
A solution is an assignment from items to bins. A feasible solution is a solution in which for each bin the total weight of assigned items is at most . The solution's profit is the sum of profits for each item-bin assignment. The goal is to find a maximum profit feasible solution.
The NFL enters Week 15 with 25-of-32 teams still in the hunt for a postseason spot. Only 14 will eventually be left standing after Week 18, meaning plenty of teams are on the chopping block ...
