🌟A more demanding course than Introduction to Mathematical Optimization. L&CO emphasizes a deeper understanding of linear and combinatorial optimization algorithms, the theory behind, proof methods, system modeling and efficient solving method. Personally speaking, it is the most eye-broadening course I've ever had at ETH. It helped me a lot in understanding the techniques commonly used in optimization from scratch in a detailed and thorough way. If you happen to have chosen Introduction to Mathematical Optimization and wish something more challenging and helpful, I would recommend you to try this L&CO instead.
🌟Don't get afraid of the credits. Just try and enjoy.
