A C implementation of the Smith massager algorithm
Ziwen Wang, Stavros Birmpilis, George Labahn +1
We describe a C implementation of the Las Vegas algorithm of Birmpilis, Labahn and Storjohann from 2020 for computing the Smith normal form of a nonsingular integer matrix. The alg…

Numerical methods for optimal decumulation of a defined contribution pension plan
Peter A. Forsyth, George Labahn
The decumulation of a defined contribution (DC) pension plan is well known to be one of the hardest problems in finance. We model this decumulation challenge as an optimal stochast…

Computing bases in Hermite normal form of lattices of integer relations
George Labahn, Arne Storjohann
Given a full column rank and an we present an algorithm to compute the basis in Hermite form of the integer lattice…
