"WebUnderstanding the Euclidean Algorithm. If we examine the Euclidean Algorithm we can see that it makes use of the following properties: GCD (A,0) = A. GCD (0,B) = B. If A = B⋅Q + R and B≠0 then GCD (A,B) = GCD (B,R) where Q is an integer, R is an integer between 0 and B-1. The first two properties let us find the GCD if either number is 0.

WebThere exists a probabilistic polynomial time (PPT) sampling algorithm Gen s.t. Gen (1 n) = ( k, tk) with k ∈ K ∩ {0, 1} n and tk ∈ {0, 1} * satisfies tk < p ( n ), in which p is some polynomial. Each tk is called the trapdoor corresponding to k. Each trapdoor can be efficiently sampled. WebIn this paper, we will firstly give a formula of the upper capacity pressure for a factor map. Then we show there is a similar relation of packing topological pressure for a factor map. As an application, we obtain that for a factor map with being finite to one or countable to one, the packing dimension is preservable under the factor map.
