An optimization problem is one where you have to make the best decision (choose the best investments, minimize your company's costs, find the class schedule with the fewest morning classes, or so on). In optimization models then, the words 'minimize' and 'maximize' come up a lot when articulating an objective. In data science, many of the practices, whether that's artificial intelligence, data mining, or forecasting, are actually just some data prep plus a model-fitting step that's actually an optimization model. We'll start with a little practice with optimization now. Just a taste. In Excel, optimization problems are solved using an Add-In that ships with Excel called Solver.

What's the fewest number of items you can buy from the snack stand to achieve that? Obviously, you could buy 10 ice cream sandwiches at 240 calories a piece, but is there a way to do it for fewer items than that? [ ] Solver can tell you!

To start, download a copy of the Calories spreadsheet from the book's companion website at -- use the download link for chapter 1. Make a copy of the Calories sheet in the Concessions.xlsx Excel workbook, name the sheet Calories-Solver, and clear out everything but the calories table on the copy. If you don't know how to make a copy of a sheet in Excel, you simply right-click the tab you'd like to copy and select the Move or Copy menu. To get Solver to work, you need to provide it with a range of cells it can set with decisions. In this case, Solver needs to decide how many of each item to buy. So in Column C next to the calorie counts, label the column How many? (or whatever you feel like), and you can allow Solver to store its decisions in this column.

Hi I try to make a search regarding similar issues but unfortunately no one face this issue before so there is no information.

First of all I want to suggest you that try to run the same code on your local mac machine and test whether you can reproduce the issue or not. I think it will work correctly on your local machine. So I guess it's because it is located in US. So the issue is in between these two locations when you try to run the code from your current location which is stored in US. I also want to suggest you to try to call the code using windows machine and check whether the same issue can be reproduce or not.

I don't have your code and environment like yours so I am not able to reproduce the issue. You can also try to post the same issue on Answers Forum.
