rlemon 0.2.1 (2023-02-06)

Interface changes

• Any function which returns a list now returns a named list. The order of elements in that list have not changed so no existing code should be affected.

Backend changes

• C++ 17 deprecations are fixed in the LEMON code.

rlemon 0.2.0 (2022-04-15)

Major changes

• MinCostFlow() now returns feasibility status (#25)
• Functions which returned 0/1 booleans now return logical instead. (#36)
• algorithm= argument to various functions has received fixes and cleanups
  • Ensure all algorithm= arguments have a default (#29)
  • Informative error if algorithm= argument isn't string (#32)
  • MaxFlow() and NetworkCirculation() properly error on invalid algorithm argument.
• MaxMatching() crashed if given NULL weights; fix such that NULL weights now yields unweighted Max Matching. (#35)
• Exported functions now interface with the LEMON library through runners. These runners aren't exported, but may be useful for users who want access to LEMON with no pre- or post-processing. See help(lemon_runners) for details. (#30)

Minor changes

• Various corrections and cleanups of documentation (#34, #27, #28, etc)
  • More precise use of the term "list", and remove usage of "boolean"
  • Fixed some links to LEMON documentation.
• Testing has been standardized to hopefully get ahead of problems in the future. (#31)
