Description

Fixed bugs

  • fixed that parameters passed on as variadic arguments to SCIPsolveNLP() and SCIPsolveNlpi() were ignored when compiling with MS compilers without -Zc:preprocessor
  • make more CONOPT output available when verbosity level is set to 2
  • turn off detection of definitional constraints in CONOPT for now, to work around a related issue in CONOPT 4.39.0
  • fixed call of SCIPcreateConsBasicSOCNonlinear() with coefs being NULL, and fixed check for offsets being finite
  • avoid crash when initial IIS solve fails while reporting errors explicitly
  • fixed that variable removal in IIS cleanup tried to delete variables that were marked as not deletable
  • fixed that some IIS info messages were not using a user's message handler
  • fixed use of interactive option (-i) of AMPL interface
  • fixed failure in nl writing on big Endian machines
  • correct memory reallocation in storeSubproblemMasterVar() of benders.c to avoid errors when freeing memory
  • also set real solution in SCIPsolSetValExact() to maintain approximation
  • handle exact solutions in SCIPsolCheckOrig(), SCIPcheckSolOrig(), and SCIPrecomputeSolObj() to correctly check exact initial solutions in SCIPtransformProb()
  • fixed calculation of Euclidean norm in calcEfficacyDenseStorage() for use in exact solving
  • removed unnecessary explicit linking of GMP library for exact solving mode unittests
  • fixed bug with changing the type of the slack variable in indicator constraints while copying
  • signal extreme estimations in timeSeriesEstimate() and skip pruning estimations in eventExecEstim() to avoid unstable restarting
  • fixed parallelism computation of dynamic cut selector to use Euclidean norm instead of unsupported argument
  • fixed that non-efficacious cuts were not filtered out before checking dynamic parallelism in dynamic cut selector
  • fixes in nauty.h for 32bit systems
  • fixed SCIPgetDualSolVal() for a linear constraint with a single variable
  • adjust conflictAnalyzeLP() to inability of row aggregation to handle a change in the number of variables
  • propagate child lower bounds back to focus node to ensure consistent lower bound tracking

Miscellaneous

  • updated ampl/mp to version 4.0.4
  • switch from GetTempPath2A to GetTempPathA in nl writer for Windows for broader compatibility
