What is the “key” which changes on every route change with connected-react-router?

When an action for navigating to a route is triggered, an action triggers a new state where the router.location.pathname changes according to the browser's history.



Another property changes as well: router.location.key, to a new random string.



The diff between two states, showing how key changes alongside a pathname.



Even when the pathname itself doesn't change (clicking on a link to a page from the page itself), the key still updates.



The diff between two states, showing how only the key changes.



What's the purpose of the key property? In which situations would I want my own state to have a randomly generated key which updates on very action dispatch? Why is it not a number which simply increments?

          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
