How to implement Composability in Java STM?

Composability:



          atomic { 

             x = Queue1.getItem();

             Queue2.getItem(x);

          }


If either getItem or putItem retries then whole transaction retries. That is the transaction waits until Queue1 is not empty and Queue2 is not full. We don't have to recode putItem or getItem.

          Dulmage-Mendelsohn matrix decomposition in Python

          Image
          0 Matlab has a function called dmperm that computes the so-called Dulmage–Mendelsohn decomposition of a n x n matrix. From wikipedia, the Dulmage–Mendelsohn is a partition of the vertices of a bipartite graph into subsets, with the property that two adjacent vertices belong to the same subset if and only if they are paired with each other in a perfect matching of the graph. Looking both on scipy and numpy, I could not find this function, nor some similar version. Is it possible to implement it using basic linear algebra operations? Any idea if this is implemented in some Python package? python matlab linear-algebra graph-theory matrix-decomposition share | improve this question
