Enum OptimisationResult 

Source 
pub enum OptimisationResult<Stop> {
    Optimal(Solution),
    Satisfiable(Solution),
    Stopped(Solution, Stop),
    Unsatisfiable,
    Unknown,
}
Expand description

The result of a call to Solver::optimise.

Variants§

§

Optimal(Solution)

Indicates that an optimal solution has been found and proven to be optimal. It provides an instance of Solution which contains the optimal solution.

§

Satisfiable(Solution)

Indicates that a solution was found and provides an instance of Solution which contains best known solution by the solver.

§

Stopped(Solution, Stop)

The optimisation was stopped by the solution callback.

§

Unsatisfiable

Indicates that there is no solution to the problem.

§

Unknown

Indicates that it is not known whether a solution exists. This is likely due to a [TerminationCondition] triggering.
