You may also find that there are languages or tools out there that are very well focused to your domain, in which case I'd very strongly advise you to make use of them if at all possible. Is your PhD about writing code to solve this problem; or about exploring the complexity and implications of algorithms; or even about actually making use of the algorithm? It all depends on what your goal is, really.
