Valerie Jean King, Jared Saia, Maxwell Young · 2011
Imagine that Alice wants to send a message m to Bob, and that Carol wants to prevent this. Assume there is a communication channel between Alice and Bob, but that Carol is capable of blocking this channel. Furthermore, there is a cost of S dollars to send on the channel, L dollars to listen on the channel and J to block the channel. How much will Alice and Bob need to spend in order to guarantee transmission of m?
