precise, give G, A, p, how to find the smallest k of gk≡a (mod p)? To simplify the problem, p is specified here as prime number.Here is an algorithm called Stride small Step (Gaint-step baby-step). The core idea of the algorithm is chunking. Take m = [sqrt (p–1)] + 1 and then represent the K as the form of XM + y (0≤y Is there a GY that satisfies Gy≡ax (GMX) –1 (mod p)?The inverse (gmx) –1 is calculated us
In addition to the GMX manual that we often see, there is a lot of information on the official website, more to see the benefits of understanding GMX, the following I put the official information on the Internet broadly listed, we look at the topic of interest:Gromacs Total is divided into the following columns about Gromacsdeveloper Zone//If you want to change the source, to read this part documentation//
