Back-and-forth method

The Back-and-Forth Method, often referred to as the Alternating Method, is a technique used to solve optimization problems, particularly in mathematical programming and control theory. This method is primarily employed when dealing with problems that can be split into subproblems where each subproblem is easier to solve independently. ### Key Features of the Back-and-Forth Method: 1. **Division of Problem**: The method involves dividing a complex optimization problem into two simpler subproblems.
