Uma nova abordagem branch and cut aplicada ao problema de planejamento da expans？o de redes de transmiss？o de grande porte

in this paper we propose a branch and cut algorithm with new inequality constraints applied to the long-term transmission network expansion problem. all the proposed inequalities in this research work are valid for both linear and nonlinear models of the problem. the computational results have demonstrated the effectiveness of the proposed method when applied to brazilian and colombian systems.
