Study Operations Research (1): Models and Applications at Coursera
To take “Operations Research” course has been on my to-do list since I was a graduate student. Even though my thesis was done by using dynamic programming and non-linear programming, I solved a scheduling problem by using integer programming in my company.However, I don’t have a chance to accomplish it due to time constraints. Now, …
