Algorithm 1 DC_Elimination( )

if (∃Edge(CKPi, DCx) ∈ IntraCDGi) then  DELETE(DCx);  REPLACE_IntraCDGnodes(CKPi, DCx); // CKPi replaces DCx  NOTICE_IntraCDGchange(CKPi, DCx);  //Notice processes the replacement of CKPi for DCx else if (∃Edge(DCx, CKPi) ∈ IntraCDGi) then if (∃Edge(CKPj, DCx) ∈ IntraCDGi ∧ CKPj ∉ Pi) then  TurnDCtoSC(DCx, SCk); // Turn DCx to SCk  NOTICE_CKPturn(DCx, SCk);  //Notice processes in same cluster of turning of DCx else  DELETE(DCx);  NOTICE_delete(DCx);  //Notice processes in same cluster of the elimination of DCx  //Notice processes in same cluster of the elimination of DCx
