Example 4 We continue with the previous example. X (1 , 2 , 2 , 2 , 1) is defined as (24).

## 4.3.2 The Pseudo-Code 

If we apply an interative method (e.g., the interior point method) to solve (10), µ may converge toward zero along the path. However, the objective function is ill-defined when µ is zero. Therefore, we define a new objective function as (25). 

Then, (9) can be reformulated as (26).
