### What does Gauss-Seidel method do?

In numerical linear algebra, the Gauss–Seidel method, also known as the Liebmann method or the method of successive displacement, is an iterative method used to solve a system of linear equations.

#### When can we use Gauss-Seidel method?

The method can be applied to any matrix with non-zero diagonal elements. However, the convergence is only possible if the matrix is either diagonally dominant, or symmetric & positive definite.

**What are the advantages of Gauss-Seidel method?**

Gauss Seidel method is easy to program. Each iteration is relatively fast (computational order is proportional to number of branches and number of buses in the system). Acquires less memory space than NR method.

**Why Gauss Seidel is better than Jacobi?**

The Gauss-Seidel method is like the Jacobi method, except that it uses updated values as soon as they are available. In general, if the Jacobi method converges, the Gauss-Seidel method will converge faster than the Jacobi method, though still relatively slowly.

## What is the difference between Jacobi’s method and Gauss-Seidel method?

The difference between the Gauss–Seidel and Jacobi methods is that the Jacobi method uses the values obtained from the previous step while the Gauss–Seidel method always applies the latest updated values during the iterative procedures, as demonstrated in Table 7.2.

### Does Gauss-Seidel method always converge?

Gauss-Seidel method is an iterative technique whose solution may or may not converge. Convergence is only ensured is the coefficient matrix, @ADnxn,is diagonally dominant, otherwise the method may or may not converge.

#### Why Gauss-Seidel is better than Jacobi?

**Which is faster Gauss-Seidel or Newton Raphson?**

It is to be noted here that both Gauss-Seidel and Newton-Raphson methods yielded the same result. However the Newton-Raphson method converged faster than the Gauss-Seidel method.

**Which is the limitation of the Gauss Seidel technique?**

What is the limitation of Gauss-seidal method? Explanation: It does not guarantee convergence for each and every matrix. Convergence is only possible if the matrix is either diagonally dominant, positive definite or symmetric.

## Is Jacobi or Gauss Seidel better?

The Gauss–Seidel method was found to be twice as effective as the Jacobi method.

### Which is better Gauss Seidel or Jacobi?

The results show that Gauss-Seidel method is more efficient than Jacobi method by considering maximum number of iteration required to converge and accuracy.
