POV-Ray uses a mix of various techniques:

- The basics are done using classic backward tracing.

- The photons feature uses some kind of forward tracing.

- Radiosity uses an algorithm first suggested by Greg Ward (Gregory J. 
Ward, Francis M. Rubinstein, Robert D. Clear, "A Ray Tracing Solution 
for Diffuse Interreflection", /Computer Graphics/, Vol. 22, No. 4, 
August 1988)


For stochastic ray tracing try MCPov.
