While Loop

• Maybe the problem is related to the "while" loop in your program. Check this structure:

Initialize Values                  

Initialize error   %(to enter the loop)

          while (error) && (logical constraints)

                   change variable

                   .....

                   .....

                   error recalculation

          end

Save the final value

• Initial Values and Initial Error and saving the final value must be into the outer loop if exists.
• % because of sensitivity to the Initial Values, the Initial values must be chosen logically or physically acceptable and meaningful
• % It also must b considered through logical constraints.
