Question
![**Problem 3**
**Objective:** Use the Branch and Bound Algorithm to solve the following integer programming problem. Also, use the simplex algorithm to solve this problem.
**Maximize:**
\[
2x - y - r
\]
**Subject to the constraints:**
\[
\begin{align*}
x - y - 2r &\leq 3 \\
x + y + r &\leq 4 \\
r &\leq 6 \\
x, y, r &\geq 0 \\
x, y, r &\in \mathbb{Z}
\end{align*}
\]
**Explanation:**
- The objective function to maximize is \(2x - y - r\).
- There are three constraints involving the variables \(x\), \(y\), and \(r\).
- The variables \(x\), \(y\), and \(r\) must all be non-negative integers.
- \(r\) must be less than or equal to 6.
- The solution involves solving this problem using both the Branch and Bound method, which is suitable for integer programming, and the simplex method, which is typically used for linear programming problems.](https://content.bartleby.com/qna-images/question/d4e7b45d-7759-4936-874e-85be62c48a7b/7254e827-9cc6-46ab-b8b2-67e3978b10e8/ju3vwn_processed.png)
