We propose the usa.e of forma. la.gua.es for expressing insta.ces of NP-complete problems for their a.plica.ion in polynomia. tra.sforma.ions. The proposed a.proa.h, which consists of using forma. la.gua.e theory for polynomia. tra.sforma.ions, is more robust, more pra.tica., a.d fa.ter to a.ply to rea. problems tha. the theory of polynomia. tra.sforma.ions. In this pa.er we propose a.methodology for tra.sforming insta.ces between NP-complete problems, which differs from Ga.ey a.d Johnson's. Unlike most tra.sforma.ions which a.e used for proving tha. a.problem is NP-complete ba.ed on the NP-completeness of a.other problem, the proposed a.proa.h is intended for extra.ola.ing some known cha.a.teristics, phenomena. or beha.iors from a.problem a.to a.other problem B. This extra.ola.ion could be useful for predicting the performa.ce of a. a.gorithm for solving B ba.ed on its known performa.ce for problem a. or for ta.ing a. a.gorithm tha. solves a.a.d a.a.ting it to solve B.
