Releases
v2.4.0
Interface changes
Changed parameters
presolve.abortfac
= 0.00080000000000000004: abort factor of weighted number of reductions for exhaustive presolving
presolve.lpabortfac
= 0.01: abort factor of weighted number of reductions for exhaustive LP presolving
New parameters with default values
numerics.useabsfeas
= 1: whether to use an absolute tolerance for feasibility checks
presolve.abortfacfast
= 0.00080000000000000004: abort factor of weighted number of reductions for fast presolving
presolve.abortfacmedium
= 0.00080000000000000004: abort factor of weighted number of reductions for medium presolving
presolve.lpabortfacfast
= 0.01: abort factor of weighted number of reductions for fast LP presolving
presolve.lpabortfacmedium
= 0.01: abort factor of weighted number of reductions for medium LP presolving
Build system
updated FindTBB.cmake
revised the CMake configuration to export the PaPILO dependencies (papilo-config.cmake
)
Fixed bugs
all fast presolvers: maintain changed activities of current and last round to avoid missing reductions
FixContinuous: only fix column which contribution deviates by at most epsilon in every row
Components: identify fixing a component to an optimal solution as strong dual reduction
You can’t perform that action at this time.
