问题描述

是否有一个在R中实现最小成本流算法的包?

igraph 包似乎只是(通过 graph.maxflow()函数),并且在这里或者在 rseek.org 看起来很有帮助。

解决方案

具有可重现的最小费用流问题的问题 here

一>。尽管我没有收到社区的明确答复,但我确实发布了我最终实施的方法。它包含 data.frame 边缘,其中 $ cost 和一个 $容量属性,然后我用它为 lpSolve 优化生成适当的约束。看看它,希望它有帮助!


Is there a package which implements a min cost flow algorithm in R?

The igraphpackage seems only to have max flows (via the graph.maxflow() function), and nothing else here or on rseek.org looks helpful.

解决方案

I was struggling with this as well and posted a question with a reproducible min-cost-flow problem here. While I did not receive a definite answer from the community, I did post the approach that I ended up implementing. It involved a data.frame of edges with a $cost and a $capacity property, which I then used to generate appropriate constraints for an lpSolve optimisation. Check it out, hope it helps!
