In computer science and mathematics, a full employment theorem is a term used, often humorously, to refer to a theorem which states that no algorithm can optimally perform a particular task done by some class of professionals. The name arises because such a theorem ensures that there is endless scope to keep discovering new techniques to ...
For instance, it showed how to solve the following problem posed by Papadimitriou and Yannakakis, for which (as of the time the paper was written) no deterministic polynomial-time algorithm is known: given a graph and a subset of the edges marked as "red", find a perfect matching with exactly k red edges.
A solved game is a game whose outcome (win, lose or draw) can be correctly predicted from any position, assuming that both players play perfectly.This concept is usually applied to abstract strategy games, and especially to games with full information and no element of chance; solving such a game may use combinatorial game theory or computer assistance.
A perfect code may be interpreted as one in which the balls of Hamming radius t centered on codewords exactly fill out the space (t is the covering radius = packing radius). A quasi-perfect code is one in which the balls of Hamming radius t centered on codewords are disjoint and the balls of radius t+1 cover the space, possibly with some ...
It can also refer to the tendency to assume there is a perfect solution to a particular problem. A closely related concept is the "perfect solution fallacy". By creating a false dichotomy that presents one option which is obviously advantageous—while at the same time being completely unrealistic—a person using the nirvana fallacy can attack ...
y 2 = x 3 + 1, with solutions at (-1, 0), (0, 1) and (0, -1). In algebra, a Mordell curve is an elliptic curve of the form y 2 = x 3 + n, where n is a fixed non-zero integer. [1]These curves were closely studied by Louis Mordell, [2] from the point of view of determining their integer points.

As a result, there is a one-to-one correspondence between Mersenne primes and even perfect numbers, so a list of one can converted into a list of the other. [ 1 ] [ 5 ] [ 6 ] It is currently an open problem as to whether there are an infinite number of Mersenne primes and even perfect numbers.
