Explanation: Computations in Jacobi's can be done in parallel but not in Gauss-seidal because in Jacobi's method, the entire set of values obtained during the previous iteration is used as it is in the next one, whereas in Gauss-seidal method, as we keep on getting the individual values of the variable, we use them in the subsequent steps. Ideally, if everything works, check[4] should output 2 (the reason for which is given in a comment in the code when outputting 'check'), and every other element of check should be 0. sum should be reinitialized to 0 inside the for-loop before starting the next row and the equation is incorrect.

The final array 'check [ ]' is obtained via a dot product between 'a' and 'x' to see if it returns something close to 'b'. The test matrix im using is A simple way to obtain initial guesses is to assume that they are all zero. new value of x is computed from the first equation in a current iteration, but What is the highest level 1 persuasion bonus you can have? (2c) to calculate a new estimate for x3. In the Jacobi's method, even though the new values of unknowns are computed in each iteration, but the values of unknowns in the previous iterations are used in the subsequent iterations.That is, although new value of x is computed from the first equation in a current iteration, but it is not used to compute the new values of other unknowns in the current iteration. Substitute this in Equation (1) and obtain the value of x1=2. This works perfectly now, Thank you. for all i, where j and j 1 are the present and previous iterations. To start with, a solution vector is assumed, based on guidance from practical experience in a physical situation. The resulting method is called Gauss-Seidel method, and the update scheme is modified accordingly to f i ( t) = 1 2 ( f i 1 ( t) + f i + 1 ( t 1)), (8) I still don't get the logic with n variable arrays not working properly, but that just means i have a lot to learn. Thus, this would seem to be very close to the correct answer. value of the variables. So how does the algorithm work? Gauss-Seidel Method is used to solve the linear system Equations. Use print statement to print the final answer for the concentrations. Convergence can be checked using the criterion, |a,i| = |xij xij-1|/|xij| 100% < s 2(c).
