Our paper about lower bound on the coded caching problem can be found here and its corresponding MATLAB code is available here that generates the lower bounds. Also, this online demo computes lower bounds based on our approach. Feel free to send me email about the code and paper. Email: ghasemi AT iastate DOT edu.
Our paper on Asynchronous Coded Caching is available here. Also, the code related to this paper can be found in my GitHub page here.
