Ok. You should install a proper python package system. Download conda https://www.anaconda.com/ . That will mean that pip install works and take it from there.

In the future, tell people what the error messages say, they might not mean anything to you, but other people can use them to figure out what's going on.

Make sure to use the editor and interpreter that come with conda rather than your existing copy of idle. This will probably be called spyder

The EdX course seems to focus more on LP theory and for example also discusses the simplex solution algorithm. That's helpful for understanding what a solver actually does you tell it to optimise your model. A downside is that they only seem to focus on continuous problems.

The Coursera course appears to be more of a tour d'horizon of mathematical programming approaches, discussing many applications and models. This is very helpful to get a broad understanding of what sorts of problems can be solved using mathematical programming models, but it does not really help you understand how these models are solved. Of course, the second and third courses in the OR specialisation will remedy this knowledge gap somewhat, but then you have to commit to more than just a single course.

I think you will learn more from the three course specialisation on Coursera, but you might also want to pick up a standard textbook on linear optimization as a reference work/aid during the course, like Bertsimas' and Tsitsiklis' book. Then you are sure to get a solid understanding of the basic mathematical programming tools used in the OR field.

You can use my Android app to see the solution steps https://play.google.com/store/apps/details?id=com.simplex

There are also explanation of the general solution process there

Yes, these are just different names for the same method designed to improve the result upon an initial basic feasible solution solved using either of these methods:

• North-West Corner Method

• Least-Cost Method

• Vogel Approximation Method

To solve problems with commented steps you can use for example a solver written by be for Android https://play.google.com/store/apps/details?id=com.simplex Or there are a lot of these available on the internent
