I recently started with some exercises of the comprehensive convex analysis and monotone operator book by Bauschke and Combettes. It is an excellent source for self-studying and a good fit for a student with EE math background.

I publish some of the solutions here to self-motivate myself to do more 😁 You can find the entry notes at

The book is written by Heinz H. Bauschke and Patrick L. Combettes. You can click on the cover below to go the Springer website. But there may be some first edition available online.
