LpSolveDotNet Release Notes

vNext -- not released yet

New Features/Improvements

  • Document enum values
  • Add missing enum values to be equal to those in lpsolve's source code.

Bug Fixes

  • Fixes issue #6: Missing enum value lpsolve_return.ACCURACYERROR with value 25
  • Fix all enum values to be equal to those in lpsolve's source code.

API changes

  • Changed value of lpsolve_msgmask.MSG_MILPEQUAL from 32 to 256 which is the value expected from lp_solve.
  • Changes to the pivot modes in the lpsolve_piv_rules enum to follow lp_solve's source code:
    • PRICE_AUTOPARTIALCOLS and PRICE_AUTOPARTIALROWS now replaced by PRICE_AUTOPARTIAL and PRICE_AUTOMULTIPLE respectively.
    • The behaviour of PRICE_AUTOPARTIAL has changed. The previous definition of PRICE_AUTOPARTIAL was PRICE_AUTOPARTIALCOLS | PRICE_AUTOPARTIALROWS but now only has the first component. If you used this previously and want to retain same behaviour, you must use lpsolve_piv_rules.PRICE_AUTOPARTIAL | lpsolve_piv_rules.PRICE_AUTOMULTIPLE.

  • Fixes issue #3: Native binaries are not copied when project is built with property OutDir=some_path.

2.0.0 1.1.0

To see all commits for this version, click here.

Was originally released under 1.1.0 but then re-released as 2.0.0 to follow semantic versioning rules.

New Features/Improvements

  • LpSolve is now a class with instance methods instead of just a static class. It still has static factory methods to create the LP.
  • Removed methods that according to lpsolve API docs were either internal or non-functioning.
  • Do not build with "unsafe" mode anymore.

Bug Fixes

  • Use right enum types to pass to methods.
  • Use IntPtr in a few more places that were forgotten.

1.0.0

  • Initial revision with lpsolve 5.5.2.0.
