This method returns a selector of value assignments to a variable that selects all values having the smallest evaluation according to the evaluator eval.

This method returns a selector of integer variables that selects all variables having the smallest evaluation according to the evaluator eval.

This method returns a selector of integer variable assignments that selects at least minNumber domain values having the smallest evaluation according to the evaluator eval. The parameter minNumber must be at least 1.

This method returns a selector of integer variables that selects at least minNumber variables having the smallest evaluation according to the evaluator eval. The parameter minNumber must be at least 1.

This method returns a selector of integer variable assignments that selects all domain values whose evaluations are in the range [min, min + tol], where min is is the minimum valuation by eval over the domain values to be evaluated. The parameter tol must be non-negative.

This method returns a selector of integer variables that selects all variables whose evaluations are in the range [min, min + tol], where min is is the minimum valuation by eval over the variables to be evaluated. The parameter tol must be non-negative.
