Instead of generate all paths, would it be possible to uniformly initiate a lot of "photons" from the sun at the beginning, and let them randomly travel and bounce around according to certain laws until energy reaches a level that is small enough to diminish. Would this way be more efficient than calculating paths?

I think we need to care about the complexity of the algorithm since we don't want our rendering to take too many time. initiate photons may generate better solution, but it will possibly more complex to calculate since you need to care about all the photons and to simulate their pathes.
