Major Features and Improvements

  • ripser_parallel can now return "flag persistence generators", i.e. vertices and edges creating/destroying bars in the barcode (#29). A new Jupyter notebook illustrates usage of this new feature.
  • Wheels for Python 3.10 have been added (#47).
  • The computation of the enclosing radius has been sped up (#28).
  • ripser_parallel can now be imported directly from gph (#36).
  • A garbage collection step which was found to negatively impact runtimes with little memory benefit has been removed (#33).

Bug Fixes

  • Sparse input with (signed) 64-bit row and column indices is now correctly dealt with by the Python interface (#34).
  • A bug causing segfaults to occur when maxdim=0 was passed to the C++ backend has been fixed (#40).
  • An algorithmic error in dealing with edges with zero weight in the 0-dimensional computation has been fixed (#43).

Backwards-Incompatible Changes

None.
