Detailed Description

This struct holds all parameters for the Solver object.

SolverParameters is only used by the Solver constructor to define solving parameters such as the trail compression or the profile level. Note this is for advanced users only.

Definition at line 190 of file constraint_solver.h.

const SolverParameters::ProfileLevel operations_research::SolverParameters::kDefaultProfileLevel [static]

Initial value:

         SolverParameters::NO_PROFILING

Definition at line 191 of file constraint_solver.h.

const SolverParameters::TraceLevel operations_research::SolverParameters::kDefaultTraceLevel [static]

Initial value:

         SolverParameters::NO_TRACE

Definition at line 192 of file constraint_solver.h.

const bool operations_research::SolverParameters::kDefaultNameAllVariables = false [static]

Definition at line 193 of file constraint_solver.h.

TrailCompression operations_research::SolverParameters::compress_trail

This parameter indicates if the solver should compress the trail during the search.

No compression means that the solver will be faster, but will use more memory.

Definition at line 200 of file constraint_solver.h.

int operations_research::SolverParameters::trail_block_size

This parameter indicates the default size of a block of the trail.

Compression applies at the block level.

Definition at line 204 of file constraint_solver.h.

int operations_research::SolverParameters::array_split_size

When a sum/min/max operation is applied on a large array, this array is recursively split into blocks of size 'array_split_size'.

Definition at line 208 of file constraint_solver.h.

bool operations_research::SolverParameters::store_names

This parameters indicates if the solver should store the names of the objets it manages.

Definition at line 212 of file constraint_solver.h.

ProfileLevel operations_research::SolverParameters::profile_level

Support for profiling propagation.

LIGHT supports only a reduced version of the summary. COMPLETE supports the full version of the summary, as well as the csv export.

Definition at line 217 of file constraint_solver.h.

TraceLevel operations_research::SolverParameters::trace_level

Support for full trace of propagation.

Definition at line 220 of file constraint_solver.h.

bool operations_research::SolverParameters::name_all_variables

Should anonymous variables be given a name.

Definition at line 223 of file constraint_solver.h.
