Single Solution

You obtain the single best solution found during the run by calling run with the syntax

[x,fval,exitflag,output] = run(...);

• x is the location of the local minimum with smallest objective function value.

• fval is the objective function value evaluated at x.

• exitflag is an exit flag for the global solver. Values:

  Global Solver Exit Flags

  2	At least one feasible local minimum found. Some runs of the local solver did not converge.
  1	At least one feasible local minimum found. All runs of the local solver converged (had positive exit flag).
  0	No local minimum found. Local solver called at least once, and at least one local solver exceeded the MaxIterations or MaxFunctionEvaluations tolerances.
  -1	One or more local solver runs stopped by the local solver output or plot function.
  -2	No feasible local minimum found.
  -5	MaxTime limit exceeded.
  -8	No solution found. All runs had local solver exit flag -2 or lower, not all equal -2.
  -10	Failures encountered in user-provided functions.

• output is a structure with details about the multiple runs of the local solver. For more information, see Global Output Structures.

The list of outputs is for the case exitflag > 0. If exitflag <= 0, then x is the following:

• If some local solutions are feasible, x represents the location of the lowest objective function value. “Feasible” means the constraint violations are smaller than problem.options.ConstraintTolerance.

• If no solutions are feasible, x is the solution with lowest infeasibility.

• If no solutions exist, x, fval, and output are empty entries ([]).
