Does anyone know about calculating feynman path integral with monte
carlo method?

In imaginary time?
Throw a dice. Chose a path according to the weight exp(-S). (hint:
Markov chain)

Makri's group at Urbana-Champaign does that to solve certain difficult
problems in large system quantum mechanics. Look up her papers. It's
nontrivial.

I'm sure people probably do it also for field theory, but I wouldn't
know where to point you. Also stock market physicists do it as well.
