Final answer:
To find the next feasible solution using the interior-point algorithm, start with the initial feasible solution and compute the search direction and step size.
Step-by-step explanation:
To use the interior-point algorithm, we start with the initial feasible solution x⁽⁰⁾ = (3, 4, 1).
Next, we need to compute the search direction and the step size.
By solving the system of equations using the interior-point algorithm, we can find the next feasible solution x⁽¹⁾.
