The question is whether or not, for all problems for which an algorithm can verify a given solution quickly (that is, in polynomial time), an algorithm can also find that solution quickly. Since the former describes the class of problems termed NP, while the latter describes P, the question is equivalent to asking whether all problems in NP are ...
Much insight in quantum mechanics can be gained from understanding the closed-form solutions to the time-dependent non-relativistic Schrödinger equation.It takes the form
The problem can be solved by reduction to the minimum cost network flow problem. [11] Construct a flow network with the following layers: Layer 1: One source-node s. Layer 2: a node for each agent. There is an arc from s to each agent i, with cost 0 and capacity c i. Level 3: a node for each task.
Simply roll it back and forth a few times across the fur-covered fabric in question. Most hair will be collected on a single swipe, but more stubborn hair might take a few additional strokes.
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?
President Donald Trump is taking a blowtorch to the rules that have governed world trade for decades. Since the 1960s, tariffs — or import taxes — have emerged from negotiations between dozens ...
The theory of computation can be considered the creation of models of all kinds in the field of computer science. Therefore, mathematics and logic are used. In the last century, it separated from mathematics and became an independent academic discipline with its own conferences such as FOCS in 1960 and STOC in 1969, and its own awards such as the IMU Abacus Medal (established in 1981 as the ...
