Distinguishing between a problem and its instances, the paper redefines the perturbational dual problem corresponding to an unperturbational dual problem, by means of explicit formulas, instead of ‘the scheme’ of ‘formal replacements’. It shows the relations between some main perturbational dual problems and the perturbational dual problems corresponding to some main unperturbational dual problems.
