邮寄 Gilbert-Steiner 问题是否凸?
最优化与控制

摘要
引入了最优网络有限 Gilbert 问题邮寄版本在概率测度集上受 Wasserstein 度量约束的凸化,为一凸泛函。该凸泛函的极小元是支撑于图上的测度。若此图为一树(即不含圈),则该树亦为相应邮寄 Gilbert 问题的极小元。还基于熵正则化提出了实现凸化 Gilbert 邮寄问题的数值算法。

备注
In this version I recognised the possibility of cycles, so the result is conditioned on at the absence of such cycles
