We have constructed a Carmichael number with 10,333,229,505 prime factors, and have also constructed Carmichael numbers with k prime factors for every k between 3 and 19,565,220. These computations ...

An efficient branch-and-bound algorithm for computing the best-subset regression models is proposed. The algorithm avoids the computation of the whole regression tree that generates all possible ...

Research from all publishers Recent studies have focused on optimising the construction of suffix arrays to address scalability and efficiency challenges. For example, novel algorithms have been ...
