I cannot understand why my address is not authorized.
I have a client and when it connects to the server, it transmits its data including the ip and port. The server in turn has to send signals to the client at a certain time (the client responds to them) But when I try to go through all the clients, an exception is thrown.
Code:



public void run() {

        ResultSet res;

        while (true) {

            try {

                Thread.sleep(5000);

                res = DatabaseHandler.getAddresses();

                while (res.next()) {

                    for (int i = 1; i <= res.getMetaData().getColumnCount() - 1; i++) {

                        System.out.println(res.getString(i) + Integer.parseInt(res.getString(i+1)));

                        try (SocketChannel sc = SocketChannel.open

                                (new InetSocketAddress(res.getString(i),Integer.parseInt(res.getString(i+1))))) {



                            ByteBuffer buffer = ByteBuffer.allocate(4);

                            buffer.clear();

                            buffer.putInt(MessageTyps.SIGNAL_REQUEST);

                            buffer.flip();

                            while(buffer.hasRemaining()) {

                            }

                            DatabaseHandler.incrementCount(res.getString(i),Integer.parseInt(res.getString(i+1)));

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
