Dekker's algorithm is a concurrent programmingalgorithm for mutual exclusion that allows two processes to share a single-use resource without conflict, using only shared memory for communication.
It avoids the strict alternation of a naive turn-taking algorithm, and was one of the first mutual exclusion algorithms to be invented.
... If the discriminant is zero, then there is a repeated solution x, and this solution is real. (Geometrically, this means that the parabola described by the quadratic ...
