Member Function Documentation

◆ bestObjectiveBound()

double bestObjectiveBound ( )

Returns the best lower bound found when minimizing, of the best upper bound found when maximizing.

Definition at line 75 of file CpSolver.java.

◆ booleanValue()

Boolean booleanValue ( Literal  var)

Returns the Boolean value of a literal in the last solution found.

Definition at line 85 of file CpSolver.java.

◆ getParameters()

SatParameters.Builder getParameters ( )

Returns the builder of the parameters of the SAT solver for modification.

Definition at line 124 of file CpSolver.java.

◆ numBranches()

long numBranches ( )

Returns the number of branches explored during search.

Definition at line 100 of file CpSolver.java.

◆ numConflicts()

long numConflicts ( )

Returns the number of conflicts created during search.

Definition at line 105 of file CpSolver.java.

◆ objectiveValue()

double objectiveValue ( )

Returns the best objective value found during search.

Definition at line 67 of file CpSolver.java.

◆ response()

CpSolverResponse response ( )

Returns the internal response protobuf that is returned internally by the SAT solver.

Definition at line 95 of file CpSolver.java.

◆ responseStats()

String responseStats ( )

Returns some statistics on the solution found as a string.

Definition at line 129 of file CpSolver.java.

◆ searchAllSolutions()

CpSolverStatus searchAllSolutions ( CpModel  model,
CpSolverSolutionCallback  cb 
)

Searches for all solutions of a satisfiability problem.

This method searches for all feasible solutions of a given model. Then it feeds the solutions to the callback.

Note that the model cannot have an objective.

Parameters
modelthe model to solve
cbthe callback that will be called at each solution
Returns
the status of the solve (FEASIBLE, INFEASIBLE...)

CpSolverStatus solve ( CpModel  model)

Solves the given module, and returns the solve status.

Definition at line 34 of file CpSolver.java.

◆ solveWithSolutionCallback()

CpSolverStatus solveWithSolutionCallback ( CpModel  model,
CpSolverSolutionCallback  cb 
)

Solves a problem and passes each solution found to the callback.
