Can you explain what exactly wouldn't be "too promising" about a
compiler that poses some difficult (NP-complete) questions in a
standard, massively popular format (integer programming), and answers
them using some simple heuristic (or perhaps an external) solver?
Skimming through that thesis, it's not as if he's shattering records
with CPLEX...
