review text: An algorithm can be performed with high relative accuracy (HRA) if it does not include subtractions (except of the initial data). The authors present parametrizations of B-matrices, Nekrasov matrices and B-Nekrasov matrices that allow to compute their determinants with high relative accuracy. Some examples are given.
