The persistent/zig-zag persistent intervals provide a
meaningful topological summary of a given filtration/sequence of
spaces. However, there often arises the need to compute sparse
generators for these intervals which serve to track the features
corresponding to the intervals. We will address this problem on two
aspects: 1) simplification of the data in order to reduce the
computational complexity while preserving the desired topological
features , and 2) computing a specific summand decomposition of the
