Simplex is one of the powerful algorithm to solve linear programming problems. With simplex, we can maximise or minimise objective function with the given list of constraint. public class Simplex { private double[][] tableaux; // tableaux private int numberOfConstraints; // number of constraints private int numberOfOriginalVariables; // number of original variables private boolean maximizeOrMinimize; private static final boolean MAXIMIZE = true; private static final boolean MINIMIZE = false; private int[] basis; // basis[i] = basic variable corresponding to row i public Simplex(double[][] tableaux, int numberOfConstraint, int numberOfOriginalVariable, boolean maximizeOrMinimize) { this.maximizeOrMinimize = maximizeOrMinimize; this.numberOfConstraints = numberOfConstraint; this.numberOfOriginalVariables = numberOfOriginalVariable; this.tableaux = tableaux; basis = new int[numberOfConstraints]; for (int i = 0; i < ...

Software Prerequisites ·           IBM DB2 Express-C ·           Java SE JDK To begin, we will need to write a Java App. An example is provided below, this app simply shows how to list all the lastname from Employee  table in Java app import java.sql.*; public class testing{  public static void main(String args[])  {        try       {              Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");              Connection con=DriverManager. getConnection("jdbc:db2: sample");              Statement stmt = con.createStatement();              ResultSet resultSet=stmt.executeQuery(" SELECT Lastname from Employee");              System.out.println("Got Results!");              while...
