    stop the iteration when Euclid norm of the residual
    vector between SOR solution and GE solution becomes less than
    1.0e-5

    The Euclidean norm of a vector ##\mathbf x=(x_1,\dots,x_n)## is denoted by ##|\mathbf x|## and defined by
    $$|\mathbf x| =\sqrt{(x_1)^2+\cdots+(x_n)^2}.$$ If you want more help, you will have to provide more details. What is the SOR solution and the GE solution?

    thank you for replying;
    SOR is : successive over-relaxation method.
    GE: Gaussian elimination with partial pivoting

    Then what it says is "run two numerical approximations, the "SOR" and "GE", simultaneously. Stop when the difference between the two solutions is less than 0.00001."
