Difference between Optimizer and Profit Optimization

Hello,

As far as I understand the difference between them is that Optimizer is minimizing costs and Profit Optimization is minimizing Gross Profit.

My question lies on if in Profit Optimization  NonDeliveryCostRate is equal to Total Saleable Price by definition,  then with both methods we should obtain the same results.

Optimizer = minimize sum of costs including Nondliverycostrate

Profit Optimizer= minimize profit which is sum of costs including TotalSaleablPrice=NondeliveryCostRate

Why is my statement wrong?  Which is the difference between them?

Thank you very much in advance.

Best Regards,
