Difficult!

Good Course, I had learn a lot of concept of optimization

The most challenging course that I've ever enrolled in. The instruction videos are just a 30% of what it takes to get perfect score on the assignments. Its the only course that I feel it was totally worth the time trying to complete it at 100%. Amazing instructor, and I'm totally gonna keep and revisit all of the course videos.

I love it so much. Rather challenging , but excellent as it is clear and pushes you to improve in the fields you need (maths, modelization , programming, algorithms)

Very difficult. Harder than pretty much all of the courses I've taken in college, more or less, based on how much material is covered and the amount of research you have to do on top of the lectures in order to just get a passing grade on the assignments. Definitely a grad level course, probably harder than most grad level courses I've taken in college just for the amount of effort needed to get a perfect score on all assignments (unfortunately it depends on how good of a computer you have to run your solutions). The challenge just makes it even more fun. Lectures barely covers anything needed to do the assignments, which just gives you a surface level introduction to the concepts needed to solve the problems. The discussion forum is crucial to getting good guidance on how to solve the problems. Pretty much all of the assignments involved doing your own research and reading a bunch of problem-related research papers to figure out what you want to use for your own implementations. I had a blast learning, and thank you so much for offering this course on coursera.

useful for optimize researcher

This is my fifth or sixt online course on coursera, and it is without a doubt the best one I have done. Apart from the little goofy start with Indiana Jones, I simple loved the course. There was a lot of useful material covering what would have been several courses at my university. The assignments were challenging, sometimes frustrating, but really fun as well. I had a lot of fun doing this course.

i wish there was 6 start rating so i can give this prof his due, he made a very complicated subject look very simple and easy to understand thanks a million

Most difficult on-line course I've ever had. Demanding and engaging at the same time. Good luck to people without IT background :D.

Great course, very challenging as problems are NP-hard and hence force you to find the right approaches for various problem set sizes. After a while, you get hooked and tried to find better and better solutions, reviewing videos for overlooked information, looking at research papers and available resources on the net. Programming times are only a minimum and I spent much more time than indicated.
