Moreover, t.ey h.ve not.considered t.e don＇t.care t.rms, wh.ch.makes t.e circuit.performance unable t. be furt.er opt.mized. In t.is paper, we propose a power and area opt.mizat.on approach.of mixed polarit.

First.y, t.e incomplet.ly specified Boolean funct.on is t.ansformed int. zero polarit. incomplet.ly specified MPRM （ISMPRM） by using a novel ISMPRM acquisit.on algorit.m. Secondly, t.e polarit. and allocat.on of don＇t.care t.rms of ISMPRM is encoded as ch.omosome. Last.y, t.e Paret. opt.mal solut.ons are obt.ined by using NSGA-II, in wh.ch.MPRM corresponding t. t.e given ch.omosome is obt.ined by using a ch.omosome conversion algorit.m. t.e result. on incomplet.ly specified Boolean funct.ons and MCNC bench.ark circuit. sh.w t.at.a significant.power and area improvement.can be made compared wit. t.e exist.ng power and area opt.mizat.on approach.s of RM circuit..
