Prototyping Is Critical for Algorithm Research

“Experience shows that the real world often breaks some of the assumptions made in theoretical research, so testbeds are an important tool for evaluation under very realistic operating conditions” “…development of a testbed that is able to test radical ideas in a complete, working system is crucial”
